 No one is immune to making mistakes – we are human, after all! But if we simply apologize and carry on as before, we're in danger of repeating the same errors.

When we don't learn from our mistakes, we inflict unnecessary stress on ourselves and on others, and we risk losing people's confidence and trust in us. In this article, we look at how to ensure that we take those lessons on board, and then use what we learn.

How to Stop Repeating Mistakes

Here are five steps to help you to learn from your mistakes, and to put what you discover into practice.


"Making a mistake" is not the same thing as "failing." A failure is the result of a wrong action, whereas a mistake usually is the wrong action. So, when you make a mistake, you can learn from it and fix it, whereas you can only learn from a failure.

1. Own Your Mistakes

You can't learn anything from a mistake until you admit that you've made it. So, take a deep breath and admit to yours, and then take ownership of it. Inform those who need to know, apologize , and tell them that you're working on a solution.

Saying "sorry" takes courage, but it's far better to come clean than to hide your error or, worse, to blame  others for it. In the long run, people will remember your courage and integrity long after they've forgotten the original mistake.

If, however, they hear of it from another source, your reputation will suffer and you may not get another opportunity to learn.

2. Reframe the Error

How you view your mistakes determines the way that you react to them, and what you do next.

Chances are, you'll view your error in a purely negative light for as long as any initial shock and discomfort about it persists. But, if you can reframe your mistake  as an opportunity to learn, you will motivate  yourself to become more knowledgeable and resilient.

When you've acknowledged your mistake, think about what you could do to prevent it from happening again. For example, if you didn't follow a process properly, consider introducing a more robust checklist or a clearer process document.

Stop beating yourself up, pause for a moment to reflect, and start thinking about how you can gain from the situation.


Your mindset plays a significant role in how you view your mistakes and, importantly, in how you react to them.

If you have a "growth" mindset, you likely see mistakes as an opportunity to improve, and not as something that you are doomed to repeat because your mindset is "fixed" on the belief that you can't improve.

You can find out how to develop a growth mindset with our article, Dweck's Fixed and Growth Mindsets .


A learning opportunity is not the same as an excuse for careless behavior!

Rather, admitting to your mistakes and showing that you have learned from them can help others to understand that making mistakes is OK. That is, as long as you act intelligently, in good faith, and keep your risk-taking within agreed boundaries.

Model this approach to encourage your people to take responsible risks, and to be more creative.

3. Analyze Your Mistake

Next, you need to analyze your mistake honestly and objectively. Ask yourself the following questions:

·         What was I trying to do?

·         What went wrong?

·         When did it go wrong?

·         Why did it go wrong?

For complex or more critical issues, a more in-depth tool, such as Causal Factor Charting , may be more appropriate.

Conducting this "postmortem" should reveal what led to the mistake, and highlight what needs to change in order to avoid a repeat.


4. Put Lessons Learned Into Practice

The danger at this stage is that work pressures force you back to your routine tasks and habitual behaviors. The lessons that you identified in Step 3 could languish, unfulfilled, as mere good intentions. In other words, learning lessons is one thing, but putting them into practice is quite another!

Chances are, acting on what you've learned will require the discipline and motivation to change your habits , or to change the way that your team works. Doing so will help you to avoid self-sabotage  in the future, and will allow you to reap the rewards and benefits of implementing better work practices .

Here, you need to identify the skills, knowledge, resources, or tools that will keep you from repeating the error.

Do so with care, though, because "quick fixes" will likely lead to further mistakes. Any actions that you take to implement your learning need to be enduring, and something that you can commit to.

If your mistake was a minor or a personal one, personal goals  and action plans  will lay the groundwork for implementing the lessons you've learned. They can give you a timescale to work to, and a list of the tasks that you'll need to complete.

The specific tools that you use from there on will depend on the particular lessons that you need to put into practice.

For example, if you learned that a mistake occurred because of your forgetfulness, aides-mémoire  or greater attention to detail  could help. If you found that your organizational skills  were below par, digital planners and spreadsheets would be useful.

Or, if you discovered that an error occurred because of a cross-cultural misunderstanding, your communication skills  might need a polish.

If the mistake was more organizational than personal, you may need to implement your learning in a more far-reaching way. Writing clearer procedures , for example, could help to ensure that more gets done without mistakes.

Understanding Zenger and Folkman's 10 Fatal Leadership Flaws  could help to tackle errors from the top. In fact, not learning from mistakes is one of the 10 flaws, and providing clear and specific feedback  is one way to counter this flaw.

And, if you learned that your new product wasn't distinctive enough to be successful, you may need to revisit your whole strategy .


Tip 1:

Learning from mistakes, and putting that learning into practice, involves change. If that change will impact other people, the ADKAR Change Management Model  could help you to get them "on board" – and to keep them there.

Tip 2:

Don't be afraid to ask colleagues or your manager for help if you're unsure which tactic or tool will be the most effective in preventing further mistakes.

Involving other people is a great way to make them feel invested – and it can be particularly important when mistakes are made at a team or organizational level. So, foster an environment where people feel comfortable about expressing their ideas.

5: Review Your Progress

You may have to try out several ways to put your learning into practice before you find one that successfully prevents you from repeating past errors. The Plan-Do-Check-Act  cycle is a great tool for pinpointing the most effective solutions.

From there, monitor the efficacy of your chosen tactic by reviewing the number and nature of mistakes that do – or don't! – still get made. Asking someone to hold you accountable  can help you to stay committed to your new course of action.


Key Points

To err is human, and we don't have to punish ourselves for the mistakes that we make. They can be great opportunities to learn, and to develop on a personal, as well as an organizational, level. We just need to learn from them, and to put that learning into practice.

When you, or one of your team members, make a mistake:

·         Own up to it. Don't play the "blame game." This is detrimental in the long run, and you'll lose the potential for learning.

·         Reframe your mistake as an opportunity to learn and develop.

·         Review what went wrong, to understand and learn from your mistake.

·         Identify the skills, knowledge, resources, or tools that will keep you from repeating the error.

·         Review your progress.

How to Be Smarter

When we’re young, life just seems to happen without us having much say in the matter. Then responsibility begins to shift from our parents to us. From that point forth, our own decisions and circumstance dominate our lives. Those two factors are largely responsible for how things turn out for us. And the two are intimately related.


We often observe how successful people make their own luck, but that’s really just another way of saying they make smart decisions when it comes to taking risks and creating or capitalizing on opportunities. So success in business – and in life, I would argue – is primarily a function of making smart decisions.


Since every decision you make is based entirely on your own thoughts and feelings –how your brain processes experiences, events, and information from a variety of sources to draw conclusions – it’s actually not that complicated to determine how to make smarter decisions. This is how you do it.


Be present in the moment.

The first time I told the story of how an ex-girlfriend’s father took me in his Porsche to visit his startup company, where I learned about the coming wave of digital electronics (that was the late 70s, mind you), I remember thinking, what if I hadn’t been paying attention to the guy?

There have since been maybe seven or eight similarly critical random events that changed my life. And if I hadn’t been engaged in the moment they would have simply passed me by. I never even would have known I missed them. And where would I be today? It’s a sobering thought.


Trust your instincts.

Using the same example, what if that simple event hadn’t resonated with me the way it did? What if I hadn’t jumped right on it without hesitation and capitalized on the opportunity? I never would have gone back to grad school, gotten into the high-tech industry, and had an awesome 20+ year career.

When it comes to decision-making, listen to what smart, knowledgeable people say but, in the end, you have to make the right call. If you learn to trust your gut, you won’t hesitate when what you’re hearing is right. And when you do hesitate, you’ll know it isn’t right.

Think critically.

The more you allow yourself to be overloaded by information, interrupted by communication, and bombarded by distraction, the less time and attention you have left to focus on what really matters and question the accuracy, efficacy, and applicability of what you’re learning and experiencing.

Let me say it another way. By opting for quantity of information, communication, and possessions over quality, you sacrifice deep understanding through logical reasoning in favor of the next shiny object, inspiring post, or other feel-good nonsense that grabs your ever-shrinking attention span.

You would not believe how much dumber that makes you. Without logical constructs like deductive reasoning and the scientific method, our society would never have progressed. There would be no technology. We’d all be stuck back in the dark ages. Stop and think about that for a minute … without checking your phone.

Stay sharp.

Every time I see some popular and unsubstantiated nonsense about a miracle diet, pill, vitamin, or nutritional supplement that’s supposed to do magical things like make you thinner or smarter, it drives me nuts. None of that stuff works, folks. They’re all scams – moneymakers courtesy of our quick-fix culture.

Look, your brain is part of your body, right? Think. Just eat a good variety of reasonably healthy stuff, don’t eat too much, get out and exercise once or twice a week, and you’ll be fine. If you keep your body in pretty good shape, guess what? Your mind will come along for the ride and maintain its plasticity as you age.

One last thing. There’s been some negative stuff about caffeine from questionable sources, lately. Don’t believe it. It’s an amazing and, read my lips, naturally occurring stimulant. For the vast majority of you, a cappuccino or a few cups of tea a day will not harm you. And it will make you sharper. No kidding. As with anything, just don’t overdo it.

Smartphones today come with a wealth of sensors to facilitate a better user experience, provide apps with enhanced information about the world around the phone and provide robust and increased battery life.

Proximity Sensor

Detects when an object is near to the phone. Most commonly used to sense when a phone is held up to the users ear to turn off the display. This saves both battery life and prevents accidental screen touches.

Accelerometer and gyroscope

Accelerometers in mobile phones are used to detect the orientation of the phone. The gyroscope, or gyro for short, adds an additional dimension to the information supplied by the accelerometer by tracking rotation or twist.

An accelerometer measures linear acceleration of movement, while a gyro on the other hand measures the angular rotational velocity. Both sensors measure rate of change; they just measure the rate of change for different things.

In practice, that means that an accelerometer will measure the directional movement of a device but will not be able to resolve its lateral orientation or tilt during that movement accurately unless a gyro is there to fill in that info.

With an accelerometer you can either get a really “noisy” info output that is responsive, or you can get a “clean” output that’s sluggish. But when you combine the 3-axis accelerometer with a 3-axis gyro, you get an output that is both clean and responsive in the same time.”

Accelerometers are also used to provide ‘steps’ information for a vendors ‘health’ application.


Digital compass

The digital compass that’s usually based on a sensor called the magnetometer and provides mobile phones with a simple orientation in relation to the Earth’s magnetic field. As a result, your phone always knows which way is North so it can auto rotate your digital maps depending on your physical orientation.



Global Positioning System (GPS) units in smartphone communicate with the satellites to determine our precise location on Earth. The GPS technology doesn’t actually use internet data this is why we can find our location on maps even after losing the signals, but the map itself is blurry as it requires internet to load the details — this is how offline map works. GPS is used in all location-based apps like Uber and Google Maps.

The accelerometer, gyroscope, magnetometer, and GPS work together to create the perfect navigation system in your smartphone.


Ambient Light Sensor

The light sensor detects the lighting levels in the vicinity to adjust the display brightness accordingly. It is used in Automatic Brightness Adjuster to decrease or increase the brightness of the smartphone screen based on the availability of light.


The microphone is basically a sound sensor that detects and measures the loudness of sound. While there are different types of microphone sensors available, smartphones generally use micro-sized electret microphones.

Apart from making and receiving calls, it is used for voice search and voice commands for digital assistant apps like Google Assistant, Siri, Cortana, etc.

Touchscreen Sensors

The smartphone sensors in a touchscreen have an electrical current passing through them at all times and touching the screen causes a change in the signals. This change acts as input for the device. Before Apple introduced the capacitive touchscreen, resistive screens were used in the display. But nowadays, the capacitive screen is used in almost all smartphones.

Fingerprint Sensor

Gone are the days of memorizing passwords and patterns to unlock your phone as many users prefer using the fingerprint scanner these days. Fingerprint sensor enables biometric verification to secure many smartphones today. It is a capacitive scanner that records your fingerprint electrically.

When you put your finger on its surface, the ridges in your fingerprints touch the surface whereas the hollows between the ridges have a slight separation. In short, it measures the varying distances and pattern between the ridges on the surface of your finger. This smartphone sensor is quite useful in apps that require authentication such as mobile payment apps.




The pedometer is used for counting steps, and fitness tracker makes use of this sensor to count the number of steps you take. Pedometers generally use the values generated by the accelerometer to monitor your movements like running or walking.

Barcode/QR Code sensors

Most of the smartphones have barcode sensors that can read a barcode by detecting the reflected light from the code. It generates an analog signal with varying voltage that represents the barcode. This analog signal is then converted to a digital one and finally decoded to reveal the information in it. Barcode sensors are useful in scanning the barcodes products or QR codes.


There are many high-end Android phones like Pixel and iPhones that include a barometer in their hardware. The barometer measures the air pressure, so it is quite useful in detecting weather changes and in calculating the altitude you’re at.

Heart Rate Sensor

Next up is the heart rate sensor that measures heartbeat with the help of LED and optical sensors. The LED emits light towards the skin, and this smartphone sensor looks for the light waves reflected by it.

There is a difference in the light intensity when there is a pulse. The heartbeat is measured by counting the changes in light intensity between the minute pulsations of the blood vessels. Many fitness and health apps use this method to calculate the heart rate.


Every smartphone comes with an inbuilt thermometer for monitoring the temperature inside the device and battery. In case a component starts overheating, the system shuts down itself to prevent any damage.

However, some handsets come with additional thermometers to measure ambient temperature. If you can recall, the Samsung Galaxy S4 bragged of thermometer that can measure temperature. Such thermometer sensors can be used by apps to detect your room temperature.

Air Humidity Sensor

Now that we are talking about Galaxy S4 let’s discuss the Air Humidity sensor as well. S4 was the first smartphone to incorporate an air humidity sensor. It could measure the humidity in the air, and the data collected by it would tell the user whether the given air temperature and humidity are optimum or not. But again, this type of sensor is used by selected handsets only.

Geiger Counter

Now, this is one smartphone sensor that you should not expect to find in common devices. In fact, there is only one phone that supports it – the Sharp Pantone 5. This handset has been released in Japan only. The Geiger Counter in it can measure the current radiation level in the area.

Final Words

There is so much of technology packed into our phones that we often take them for granted. But these are some of the most important smartphone sensors that you should know of. Given that smartphones are getting smarter day by day and sensors play a major role in it, this list is will definitely grow longer and I will keep adding more to it. In case there is a smartphone sensor I forgot to mention in this article, do let us know in the comment section below!

Tesla and other car companies are selling a record number of electric vehicles (EVs). But even at
souped-up “supercharger” stations, the cars still require more than 1 hour to top off their
batteries. A new advance may change that.
One strategy for boosting battery charging speeds has been to raise the battery temperature
during charging, which accelerates the chemical reactions inside the battery. But keeping
batteries at high temperatures can cause components to break down quickly.
Now, researchers report they can prevent this breakdown, and allow fast charging, if the heat
is added just for short periods. By heating up a charging device to 60°C for just 10 minutes,
they were able to speed the incorporation of lithium ions into layers of graphite that make
up the anode (as shown in the above artist’s representation), the key step in recharging the
battery. If scaled up, this would allow them to add 320 kilometers in driving range to
conventional lithium-ion batteries, they report today in Joule. The heated batteries
were also stable, able to go through 1700 charge-discharge cycles with little degradation.

Next up, the researchers are looking to cut their charging time in half, adding enough juice
to power an EV in just 5 minutes.

Ninety-nine per cent of all freshwater ice on Earth is sitting on top of Greenland and Antarctica, and
each year, a little more of it melts into the ocean.
Normally, it would take hundreds to thousands of years for it all to melt away. But what if something
happened that caused a massive global melt overnight?
As we slept, sea levels would rise by a whopping 66 meters. Coastal cities like New York, Shanghai,
and London would drown in the apocalyptic mass flood, forcing up to 40 percent of the world's population
out of their homes.
While all this chaos ensues above-ground, something equally sinister is happening below. All that rising
saltwater will infiltrate
groundwater reserves farther inland, forcing its way into nearby freshwater aquifers.
You know, the ones that supply our drinking water, irrigation systems, and power-plant cooling systems?
All those aquifers would be destroyed. Not good.
On top of that, the ice on Greenland and Antarctica is made of freshwater, so when it melts, that's about
69 percent of the world's freshwater supply that's going straight into the oceans. This will wreak
havoc on our ocean currents and weather patterns.
Take the Gulf Stream, for example. It's a strong ocean current that brings warm air to northern Europe
and relies on dense, salty water from the Arctic in order to function. But a flood of freshwater would
dilute the current and could weaken or even stop it altogether.
Without that warm air, temperatures in northern Europe would plummet, and that could spawn a
mini ice age, according to some experts.
That's not even the worst of it. Take a look at what will happen when that last 1 percent of freshwater
ice that's not part of Greenland or Antarctica thaws. Some of that 1 percent is sitting in glaciers farther
The Himalayan glaciers specifically pose one of the largest threats because of what's trapped inside:
toxic chemicals like dichlorodiphenyltrichloroethane, or DDT. Scientists discovered that glaciers
like this can store these chemicals for decades. But as they thaw, those glaciers release the chemicals
into rivers, lakes, and groundwater reserves, poisoning each one as they go.
The rest of that 1 percent is hanging out underground, mostly in the Arctic tundra, as something
called permafrost. Permafrost is organic matter that's been frozen in the ground for two-plus years.
Now, one of the most immediate problems with thawing permafrost would be mercury poisoning.
That's right: There are an estimated 15 million gallons of mercury stored up in the Arctic permafrost.
That's almost equal to the amount of mercury everywhere else on Earth.
On top of that, the organic matter in permafrost is a tasty meal for microorganisms. After they digest it
all, they fart out two of the most potent greenhouse gases out there, carbon dioxide and methane.
Scientists estimate this could double the current levels of greenhouse gases in the atmosphere, and
potentially cause global temperatures to rise by 3.5 degrees Celsius compared to today.
That might not sound like much, but say goodbye to that mini European ice age, and even rivers
and lakes around the world. They'd evaporate from the higher temperatures and cause mass droughts
and desert-like climates. And all that extra water vapour in the atmosphere would fuel more frequent
and stronger storms, floods, and hurricanes.
So all of that newly established coastline on the eastern US would be one of the last places you'd want
to live. Instead, there would be mass migrations to Canada, Alaska, the Arctic, and even what's left
of the Antarctic.
And you're right, this is probably never going to happen. After all, there's enough ice right now to cover
the entire continent of North America in a sheet a mile thick.
So the next time you hear about record-breaking heat or ultra-powerful hurricanes, at least you know
that it could be worse. But scientists estimate that if we don't take action and global temperatures
increase by just 1 degree Celsius, the effects of climate change we already see today will be irreversible.
So yes, it could be worse, and it will be if we're not careful.
This is a transcript of the embedded video.
