How to Stop Overthinking Everything (When Your Brain Won’t Let Up)

Overthinking isn’t a character flaw – more often it’s a brain that never learned how to stop checking and won’t let up. By definition overthinking is the unproductive habit of analyzing or worrying about a situation, past mistake, or future event to an excessive degree without reaching a solution.

The fix isn’t fewer thoughts. It’s a creating a different relationship with the ones you can’t stop having. The truth about overthinking is evident in the research; rumination makes your real-time performance worse, not better.

Maybe this sounds familiar… You reread the text over and over, looking for the tone you didn’t mean. You rewrite the email in your head after you’ve already sent it. You lie awake running tomorrow’s game, meeting, activity, or pending conversation on a loop, long after there’s anything left to plan.

That’s not diligence or caring greatly – that’s overthinking. And if you’re a perfectionist, an athlete, or someone who’s built a life on getting it right, you already know how terrible it feels from the inside. So let’s talk through how you can begin to stop overthinking everything. It starts by understanding the function of it a little better.

Is Overthinking Random? Nope. It’s the “Overs”…

I call this pattern the “overs” — overanalyzing, overthinking, overpreparing, overjudging, over and over again. It doesn’t happen because you’re bad at managing your mind. It happens because somewhere along the way, your brain learned that scanning harder equals controlling more. If you’re a perfectionist, an athlete, or someone who’s built a life on getting it right, that lesson got reinforced a thousand times over.

You call it being thorough. You call it just wanting to get it right. You call it being prepared. It’s still overthinking. It’s just overthinking wearing a performance costume.

Is Overthinking Just Perfectionism in Disguise?

Overthinking and perfectionism run the same circuit. Perfectionism sets the standard. Overthinking keeps checking whether you’ve met it.

That’s why the same person who overthinks a text message also overthinks a competition strategy, a work deliverable, or something they said three years ago. It was never really about the topic. Rather, it’s a nervous system that never gets the signal that it’s safe to stop checking — I go deeper on that connection on my perfectionism and fear of failure page.

Why Athletes Overthink More Than Almost Anyone

Athletes live in a world that rewards obsession, focus and drive. Watch the film, replay the mistake, analyze the split… That’s useful after the fact, but it can be performance limiting mid-competition.

For athletes I work with, overthinking can look like:

• Replaying a bad rep while the next rep is already happening
• Thinking about the last mistake instead of responding to what’s happening now
• Pre-deciding failure before the race even starts
• Trying to consciously control movements the body already knows how to perform
• Constantly evaluating whether you’re performing “well enough”
• Getting caught in “what if” thoughts during competition

This is where mental performance training becomes so important. (Read more on Race Day Nerves to hear how it not only helps my clients, but helped me hit a huge PR and solidify qualifying for the Boston Marathon)

You don’t want an athlete who never thinks. You want an athlete who can recognize when thinking is useful and when it’s getting in the way. That’s exactly the kind of mental skill I coach with athletes, including the women’s soccer program at UW-Eau Claire, where I serve as their Mental Performance Coach.

You can read also more about how I work with competitive athletes on my sports performance and athlete mental health page.

Does Overthinking Help You Perform Better?

Not necessarily. And that’s the part worth sitting with. Overthinking feels productive while you’re doing it. It feels like problem solving, preparing, preventing mistakes. But repetitive rumination can actually interfere with the mental resources you need to perform effectively.

Research has linked rumination with diminished performance monitoring, suggesting that getting caught in repetitive thought can make it harder to accurately track performance in real time (Rumination Is Associated with Diminished Performance Monitoring, National Library of Medicine).

Research on academic stress has also found that repetitive self-focused thinking can contribute to burnout under pressure, potentially draining cognitive resources that are needed for effective performance (Frontiers in Psychology, 2024).

They is understanding that thinking isn’t bad – reflection is useful, rumination is different. Reflection looks like “what can I learn from this?” and rumination is “what if I had done something differently?” Reflection has a stopping point and rumination keeps looking for an answer that might not even exist.

That’s why learning how to stop overthinking isn’t about becoming less thoughtful; it’s learning when thinking has stopped being useful, effective, or helpful.

How Do You Actually Stop Overthinking Everything?

You can’t necessarily out-willpower a brain that’s learned to scan for problems. But you can change what you do when the scanning starts – and that’s a skill that requires doing the “mental reps”. Here are some options that I work on with my clients:

1. Name the Thought Instead of Reacting to It

When you’re overthinking, your brain presents thoughts as problems that need immediate solutions. It generates thoughts like: Did I mess that up?”, “What if they think I’m incompetent?”, “What if I fail?, “Why did I say that?”

Instead of immediately engaging with the questions, try creating some distance:

“I’m having the thought that I messed that up.”

Or:

“I’m noticing my mind is telling me I need to figure this out.”

This is a core skill in Acceptance and Commitment Therapy (ACT) called cognitive defusion. You aren’t trying to argue with the thought – you’re simply noticing it as a thought. That small shift creates space between you and the story your mind is telling. And that space is where choice becomes possible.

2. Give Your Overthinking a Container

Overthinking loves unlimited time. If you give your mind an entire evening to analyze something, it will probably use the entire evening. Instead, create a container.

Set aside a short, specific period to think through the issue. Write down what you’re concerned about. Identify anything you can actually do about it.

Then stop.

This isn’t about suppressing thoughts. It’s about teaching your brain that every thought does not require immediate attention. When the thought returns later, you can remind yourself:

“I’ve already given this some attention. I don’t need to solve it again right now.”

Then stop again. Building the container and giving yourself a “worry time out” is a strategy to practice. It doesn’t eliminate the thoughts, but rather gives them a place to be held lightly.

3. Trade “What If?” for “What’s Next?”

Overthinking lives in hypotheticals.

• What if I fail?
• What if they are upset with me?
• What if something goes wrong?
• What if I should have done something differently?

Performance and meaningful action happen in the present, so when you notice yourself spiraling, ask: What’s the next thing that needs to happen?

Not the next thing you need to figure out. Not the next scenario you need to mentally rehearse.

The next physical, concrete action.

Send the email, start the warm up, take the next step. Go to bed, have the conversation; then return your attention to what is actually happening.

4. Stop Trying to Get Rid of the Thoughts

I know, this one feels counterintuitive. The truth is, the more desperately you try NOT to think about something, the more attention you give it. Think of it like your thoughts are a plant – and overthinking waters the plant to grow and grow and grow…

So the goal is not to stop overthinking, it is to increase your self-awareness so that you notice the overthinking is happening without “watering the plant”. That’s a very different skill.

Your thoughts can be loud without demanding your attention. They can be uncomfortable without being emergencies. And they can be present without determining what you do next. You can use a simple tool called NAME:

• Notice
• Acknowledge
• Make room
• Expand

Notice that the thought exists, Acknowledge that is is a thought, Make room for the thought to exist, Expand your awareness of the thought and take an action forward.

How To Get Rid of Overthinking?

If you tend to overthink, you may have spent years trying to find the perfect strategy for finally quieting your mind. Well, hate to bear some bad news – you don’t actually get rid of your thoughts – you learn how to struggle with them less.

Some things you may have tried:

• Distraction
• Reassurance
• Preparation
• Research
• Analysis

And sometimes those strategies work temporarily. But if your brain’s fundamental rule is “I need to figure this out before I can feel okay,” you’ll eventually find something else to think about.

The deeper shift is learning that you don’t need to resolve every thought before you can move forward. Two things can go exist:

You can have uncertainty and act anyway.

You can feel anxious and stay present.

You can make a mistake and keep going.

You can have a thought without turning it into a problem to solve.

In Summary…

You don’t need fewer thoughts. You need to learn hold them more lightly instead of clutching them tightly.

That’s the actual skill – changing your relationship with your thoughts. And like any skill, it gets easier with practice and what I call “doing the mental reps”.

If this sounds like your daily life, book a free consultation and let’s start closing the gap between the mental noise and the life you actually want to be living.

FAQ

What is the definition of overthinking?

Overthinking is getting stuck analyzing, replaying, or predicting instead of acting — turning a decision, a mistake, or a worst-case scenario over in your head long after it’s given you anything useful. It’s not deep thought. It’s the “overs” in motion: your brain running the same lap again and again and calling it progress.

How do I stop overthinking everything?

You don’t need to stop thoughts from showing up. Instead, practice changing your relationship with them. Name the thought instead of automatically believing or answering it, give repetitive thinking a defined container, and redirect your attention toward the next concrete action.

Is overthinking a sign of anxiety or perfectionism?

It can be associated with both anxiety and perfectionism, although overthinking itself isn’t a diagnosis. For many people, overthinking is fueled by a desire for certainty, fear of making mistakes, or worry about how others perceive them. When overthinking is consistently driven by a need to get things exactly right, perfectionism may be part of the pattern.

How do I stop overthinking at night?

Start by separating problems that can actually be solved tonight from thoughts that are simply asking for certainty. Write down anything that requires action tomorrow, then practice noticing returning thoughts without continuing the mental conversation. The goal isn’t to force your mind to be quiet; it’s to stop treating every thought as something you need to solve before you can rest.

How do I stop overthinking mistakes?

First, separate reflection from rumination. Ask yourself, “Is there something useful I can learn or do differently next time?” If there is, identify it and move on. If there isn’t, continuing to replay the mistake is unlikely to change what happened. Practice acknowledging the thought, allowing the discomfort, and returning your attention to the present.

Can overthinking ever be useful for high performers?

Absolutely. Reflection, analysis, preparation, and reviewing performance can all be valuable for high performers and athletes. The difference is whether the thinking has a purpose and a stopping point. Useful reflection helps you learn and make an adjustment. Overthinking keeps searching for certainty, reassurance, or a perfect answer that may not exist.

What’s the difference between overthinking and problem-solving?

Problem-solving is directed toward a specific problem and usually leads to a decision or action. Overthinking tends to repeat the same questions without producing a meaningful next step. A useful question to ask is: “Is this thinking helping me do something, or am I just thinking about thinking?”
