How to Trust Yourself When You Keep Second-Guessing Everything

You make a decision.

For a few minutes, perhaps even a few hours, it feels settled.

Then the reopening begins.

What if you missed something? What if the other option was better? What if the person you spoke to was right? What if you regret this? What if the fact that you are still thinking about it means you chose badly?

And just like that, a decision that was finished is back on the table.

There is nothing wrong with reconsidering a choice when something important changes. Good judgement includes being willing to revise your position when new information appears.

But second-guessing is different.

It often means reopening a decision without any genuinely new information because uncertainty still feels uncomfortable.

Self-trust is not believing you will always make the right decision. It is trusting that you can make a reasonable choice with the information available, tolerate the uncertainty that remains, and deal with what happens next.

Why do I keep second-guessing myself?

A decision usually asks you to give something up.

Choose one job and you do not choose the other one. Say yes and you close off the version of events created by saying no. Buy the house and another house remains unbought. End the relationship and you lose the future in which you stayed.

Even relatively ordinary decisions contain alternatives.

Before you decide, those alternatives are possibilities. After you decide, they can become comparisons.

Your mind can now construct an imaginary version of the option you did not choose — and, conveniently, that imaginary version does not have to include any of its drawbacks.

The new job you declined becomes wonderfully fulfilling. The city you did not move to somehow has cheaper rent, better weather and more interesting people. The meal you nearly ordered looks excellent when it arrives at the next table.

Human beings have a remarkable ability to compare reality with alternatives that have never had to survive contact with reality.

Psychologists use the term counterfactual thinking for thoughts about how things could have turned out differently. It can help us learn from experience and make sense of regret, but repeatedly comparing what happened with imagined alternatives can also keep a decision psychologically open long after it is practically closed.

The problem is not that your mind considers alternatives.

The problem is when considering alternatives stops teaching you anything.

Reconsideration is useful. Re-litigation is not.

The first can improve judgement.

The second may simply be an attempt to make uncertainty disappear.

And that is difficult because many real decisions do not come with enough information to make uncertainty disappear.

You can research a new job. You can speak to people who work there. You can compare salary, commute, progression and culture. You can ask sensible questions.

Eventually, however, you reach a point where the remaining question is something like: Will I actually be happier there?

No spreadsheet can answer that in advance.

This is where people sometimes mistake more thinking for more information.

They are not the same thing.

You can think about the same evidence for another three hours without acquiring a single new fact.

Self-trust does not mean always being right

You will often hear the advice: trust your gut.

Sometimes that is useful. Sometimes it is not.

A feeling can contain experience, preference, fear, habit or pattern recognition, and those things do not all deserve equal weight.

A more useful form of self-trust is not I should believe every feeling I have.

That is less dramatic than believing your instincts are always right.

It is also much more realistic.

Research on metacognition — our ability to evaluate our own thinking — shows that confidence and decision quality are related but not identical. Confidence is itself a judgement, and it can sometimes diverge from how accurate a decision actually is.

So feeling completely certain is not a prerequisite for making a sound choice.

And feeling uncertain does not prove that your choice is unsound.

Why uncertainty keeps the decision open

Second-guessing often becomes strongest when the decision matters and the outcome cannot be guaranteed.

This overlaps with the same uncertainty problem discussed in Why Do I Always Imagine the Worst?.

If your mind strongly dislikes not knowing what will happen, reopening the decision can create the temporary sense that you are doing something useful.

Perhaps one more comparison will reveal the answer. Perhaps one more conversation will remove the doubt. Perhaps one more night thinking about it will produce certainty.

Sometimes it does.

Often it does not.

The important question is whether new information is still arriving or whether the same uncertainty is simply being examined from slightly different angles.

You are no longer trying to find the perfect answer.

You are deciding whether you have enough information to act.

Other people’s advice can help without becoming your decision

Second-guessing often involves another person.

You make a choice. Then somebody raises an eyebrow.

Suddenly your carefully considered decision has the structural integrity of wet cardboard.

Other people’s perspectives can be extremely useful. They may notice something you missed. They may know more than you. They may challenge a comfortable assumption.

But useful advice and delegated judgement are not the same thing.

A practical question is: Am I asking this person for information, perspective or permission?

Those are three different requests.

Information adds facts. Perspective helps you see the problem from another angle. Permission asks somebody else to remove the responsibility of choosing.

There are situations where somebody else genuinely should have more influence — a doctor discussing treatment, a solicitor advising on a legal matter, or another specialist working in an area outside your expertise.

But in many personal decisions, you eventually have to take other people’s input back into your own judgement.

Self-trust does not mean refusing advice. It means advice becomes input, not automatic instruction.

What if I make the wrong decision?

You might.

That is the uncomfortable answer.

There is no version of self-trust that guarantees otherwise.

You will misunderstand situations. You will occasionally overestimate something. You will sometimes ignore a signal you later wish you had taken seriously. And there will be decisions where you do everything reasonably and still dislike the outcome.

This is why self-trust rests less on I know I will choose correctly and more on I trust myself to respond if the choice does not work out.

That includes changing course, apologising, learning, asking for help, leaving, trying again, or admitting that you got something wrong without turning one mistake into a permanent judgement about your capacity to choose.

That is a sturdier form of confidence.

When second-guessing becomes more than ordinary indecision

Almost everybody reconsiders decisions.

That alone is not a mental-health problem.

But if decision-making repeatedly becomes overwhelming, causes significant distress, leads to persistent reassurance-seeking or avoidance, or interferes substantially with everyday life, it may be useful to discuss it with a qualified mental-health professional.

NHS Every Mind Matters has a practical problem-solving guide that separates problems you can act on from hypothetical worries and provides a structured way to work through what can actually be changed.

The goal is not to become someone who never doubts themselves.

People with no doubts at all can create their own difficulties.

The aim is to develop enough trust in your decision-making process that every uncomfortable feeling does not automatically trigger another trial.

You do not need certainty to move forward

Sometimes there is more to learn.

Ask another question. Get another opinion. Check the numbers. Sleep on it.

But eventually, many decisions reach a point where another hour of thought is simply another hour of thought.

No new evidence has arrived. No assumption has changed. The future has not become more predictable.

The decision is simply still uncomfortable.

That is often the moment self-trust becomes relevant.

Not as a dramatic declaration that you know exactly what you are doing.

More quietly:

I have thought about this carefully enough.

I know what matters to me.

I understand that I could still be wrong.

And I am willing to choose.

Because trusting yourself does not mean never questioning your judgement.

It means knowing when the questioning has done its job.
