Two decades ago, a founder began overthinking a business from his garage.

He obsessed over everything. Customer behavior. Logistics. Pricing models. Distribution networks. Thousands of operational details that most people won’t give a second thought.

From the outside, it probably looked excessive. Perhaps even unhealthy.

I never met his family, but I wouldn’t be surprised if at least a few people around him thought he was overthinking things. After all, how much time can one person spend obsessing over books, warehouses, delivery systems, and customer experience?

Today, we call that business Amazon. One of the most successful businesses ever built in our living memory. And that founder was Jeff Bezos.

Here is another one.

Albert Einstein, one of the most influential scientists in human history, spent years wrestling with questions about space, time, gravity, and the very nature of reality itself. There were long periods where progress was painfully slow, and answers seemed nowhere in sight. Yet he kept returning to the problem, examining it from different angles, chasing ideas that most people would have abandoned long before.

For nearly a decade, he remained obsessed with questions he couldn’t answer.

Eventually, that obsession produced the Theory of Relativity and fundamentally changed our understanding of the universe.

As you think about examples like these, you’re almost forced to consider a fundamental contradiction about the way overthinking is adjudged in our societies.

If overthinking and obsession were simply the act of thinking too much, then surely these people would qualify as some of the world’s biggest overthinkers. And if that were true, many of the breakthroughs, discoveries, and innovations that shape our lives today might never have existed.

But that’s clearly not the case.

Thinking Is A Tool

The above contradiction starts to make a little more sense when you realize that thinking more, in itself, has never been the problem.

After all, nobody tells a scientist to stop thinking. Nobody dare tell an entrepreneur to stop thinking excessively about his product or service.

Nobody tells a surgeon to stop thinking halfway through a complicated operation.

In fact, if you’re about to undergo surgery, you’d probably prefer a doctor who has spent an uncomfortable amount of time evaluating everything that could go wrong.

Thinking is one of our most powerful capabilities. It allows us to solve problems, learn from mistakes, anticipate consequences, and navigate an increasingly complex world.

The problem is that we often assume solving problems and predicting outcomes are the same thing.

And that’s where things begin to get interesting.

Imagine that you and I are sitting together trying to solve a mathematics problem. Thinking helps in this case. More thinking often helps even more. The better we understand the problem, the greater the probability that we eventually find a solution.

Now imagine that instead of solving a mathematics problem, you’re trying to figure out whether somebody likes you, whether your relationship will survive the next five years, whether your business idea will work, or whether your career decision today will turn out to be the right one ten years from now.

Notice how different these problems are.

The first category requires answers waiting to be discovered.

The second category contains uncertainty. It requires predicting outcomes for things not entirely in our control.

Yet most of us try resolving both types of problems with the same process.

We sit down and think harder. Then harder still. We replay conversations. We imagine future scenarios. We mentally rehearse outcomes that may never happen.

Somewhere in this process, thinking quietly stops creating clarity and starts creating noise.

That’s when productive thinking transforms into overthinking.

Not when you’ve spent too much time thinking. But when you’re asking your mind to do something it was never designed to do.

To eliminate uncertainty.

The Certainty Trap

One of the strangest things about human beings is that we often demand guarantees from situations that were never designed to provide them.

Before making a career change, we like to know whether we’ll enjoy the new one. If, before starting a business, someone could let us know whether it will succeed, that’d be awesome. Further, when it’s time to make a major life decision, if only someone could inform us whether we’ll regret it five years from now or not, that’ll make it much easier.

However, life in a nutshell is not that cooperative.

In other words, we are expecting answers to questions that only time can answer. And that’s where the trap begins.

Because when an outcome of a choice isn’t clear, most of us don’t feel comfortable with uncertainty. We simply start thinking harder.

We replay conversations, analyze possibilities, and mentally simulate all possible scenarios like an unpaid intern working overtime inside our own heads.

The strange part is that this feels productive. After all, we’re doing something. We’re gathering information, evaluating options, and considering consequences. From the inside, it feels responsible.

But thinking and progress are not always the same thing. Or as Lyor Boone from the Designated Survivor will put it – “You’re confusing motion for progress.”

Sometimes you’re moving closer to a decision. Most times, you end up moving in circles around it.

At some point, irrespective of its nature, every decision or choice reaches a stage where further evaluation doesn’t add value but creates noise. Beyond that point, the goal should not be to achieve clarity or certainty. The goal should be to feel confident and adaptable enough to move forward despite a lack of clarity or certainty.

Because uncertainty is not a flaw in life. It’s one of its default settings.

And the sooner you stop demanding guarantees from an uncertain world, the less power overthinking tends to have over you.

Why do we all keep Falling For It?

It’s quite easy to assume that overthinking is simply a bad habit. The reality is a little more interesting.

In fact, our brain is doing exactly what it was designed to do.

One of the primary responsibilities of the human brain is to help us navigate uncertainty. Researchers have found that uncertainty influences attention, learning, memory, and decision-making in profound ways.

In simple terms, when something feels uncertain, our brain automatically treats it as important. It allocates more attention to it, spends more energy evaluating it, and keeps returning to it in an attempt to reduce the unknown.

From an evolutionary perspective, that makes perfect sense.

If our ancestors heard a strange sound outside a cave at night, ignoring it completely wasn’t a particularly successful survival strategy. Paying attention to uncertainty often increased the odds of survival.

The problem is that modern uncertainty rarely looks like a predator hiding in the dark. Instead, it looks like an evolved career or life decision.

A relationship. A business risk. An unanswered text message. A future that refuses to reveal itself in the present.

And because our brain isn’t wired to ignore unanswered questions, it keeps returning to them. It doesn’t enjoy making us miserable, but it has evolved to believe that it is simply helping. Therefore, overthinking becomes such a convincing trap.

Every time you revisit the problem, it feels like progress. You’re gathering information. Evaluating possibilities. Looking for clues. The mind interprets all of this activity as productive work.

Turning Overthinking Back Into Thinking

One needs to have focused awareness to notice the exact point when productive thinking transforms into overthinking. It usually happens quietly.

Let’s say you’re sitting with a problem that genuinely deserves your attention. Something important enough that it would be irresponsible not to think about it.

So you do what any rational person would do. You evaluate your options and consider a few possible outcomes.

Then a few more.

And then a few more.

If you pay attention, somewhere along the way, something strange happens. You stop gathering information and start recycling it.

The same thoughts resurface in your mental space, probably in different clothes. Same concerns return in slightly different languages, playing repeatedly like a movie you’ve already seen twenty-seven times.

At that point, or probably long before this stage, productive thinking has already served its purpose.

The purpose of thinking is not to keep you occupied but to help you make an informed decision. Once you’ve collected all the necessary information, considered the variables that matter, and rationally arrived at a conclusion supported by the evidence in front of you, thinking has largely completed its role.

Everything after that is a sleezy attempt to derive certainty from data that cannot provide it.

Over time, and especially after a long chain of thoughts, here is one of the most useful questions I’ve ever learned to ask myself. And it’s surprisingly simple:

“Am I learning something new, or am I merely revisiting something I already know?”

In my experience, if you’re no longer learning, discovering, or deciding, there’s a good chance you’re no longer thinking.

You’re overthinking.

In that case, the solution is rarely to keep thinking. More often than not, it’s action.

Final Thoughts

Let’s go back to the question we started with.

If overthinking were simply the act of thinking too much then Jeff Bezos should have failed long before Amazon became Amazon. Albert Einstein should have abandoned his work long before he fundamentally changed our understanding of the universe.

But that’s not what happened.

Because neither of them had an overthinking problem. They had problems worth thinking about. Both of them used productive thinking as a tool. 

Thinking is valuable and productive when it helps us understand reality better. It becomes destructive when we start using it to negotiate with reality itself, or maybe force the results of outcomes that have too many external variables. 

At one point or another, we all fall into the certainty trap.

We all convince ourselves that another hour of thinking, another round of analysis, or another mental rehearsal will somehow reveal the answer we’ve been searching for.

Beyond a certain point, thinking stops creating clarity and starts creating noise.

The irony is that life never demands or provides certainty. It only requires informed decisions.

Every meaningful choice comes bundled with risk, ambiguity, and incomplete information. There is no workaround for that. No hidden level of intelligence that suddenly grants access to all future outcomes.

The best we can do is gather the information available, think honestly about what we know, acknowledge what we don’t know, and then move forward anyway.

Eventually, every important decision will reach a stage where no amount of additional thinking would help. Only action could.

And perhaps that’s the simplest way to distinguish productive thinking from overthinking.

One moves you closer to a decision. The other keeps you trapped in the waiting room.
