How to Stop Second-Guessing Yourself: 8 Ways to Trust Your Decisions

You sent the email and immediately wonder whether it sounded wrong. You chose the blue one, and now you are pretty sure the green one would have been better. You made the decision last week and still replay it at night. Every choice, once made, seems to open a trapdoor of “what if.”

Second-guessing is exhausting, and it feels responsible. But more doubt does not usually mean better decisions; it means more suffering over the ones you have already made.

Why we second-guess

Fear of regret

We imagine how bad it would feel to have chosen wrong, so we keep checking. Neal Roese and Amy Summerville found that people tend to regret inactions and missed opportunities more in the long run than actions, which shows that regret is not simply a risk of acting.

Maximizing

Barry Schwartz and colleagues distinguished maximizers, who try to find the best possible option, from satisficers, who choose something good enough. Across several studies, maximizers reported lower happiness, less satisfaction, more regret and more depression-related symptoms, even when their objective outcomes were as good or better. The search for the perfect option fuels endless comparison.

Too many options

When there are more choices, each alternative seems like a missed chance. See how to make decisions when you’re unsure.

Perfectionism and fear of judgement

If mistakes feel unacceptable or you worry what others will think, you keep checking. See how to stop being a perfectionist and how to stop seeking approval from others.

Past experiences

If an earlier decision went badly, or you were criticised for mistakes, you may not trust your own judgement now. See how to stop living in the past.

Anxiety and overthinking

Anxious minds search for certainty that does not exist. See how to stop overthinking.

Keeping options open feels safer

Daniel Gilbert and Jane Ebert found that people prefer decisions they can change, and expect to be happier that way, but are actually less satisfied with changeable choices than with final ones. When a decision is irreversible, the mind gets to work making peace with it. Open doors keep the mind busy.

What second-guessing costs

• hours of mental energy,
• delayed or avoided decisions,
• less satisfaction with what you chose,
• strained relationships when others are asked to reassure again and again,
• lower confidence in your own judgement.

8 ways to stop second-guessing yourself

1. Decide what matters before you choose

List the two or three things that matter most (cost, time, values, risk). When you have those criteria, you can check the option against them once instead of reopening the whole question.

2. Aim for “good enough”

Define “good enough” in advance: Does this meet my criteria? If yes, you are done. Satisficing is not settling; it is a strategy that research links with greater wellbeing. Ask: Is the gain from more searching worth the cost?

3. Set a deadline and a limit on research

Give yourself a time limit (“I’ll decide by Friday”) and a research limit (“I’ll look at three options”). Without limits, the search expands to fill any space.

4. Ask for limited input

Consult one or two people you trust, not twelve. More opinions often add confusion. Ask for information, not permission. See how to stop needing constant reassurance.

5. Sort decisions by reversibility

Ask: Can I change this later? Most decisions are reversible or low-stakes, so decide quickly and adjust. Reserve more thought for the few that are not.

6. Commit and close the door

After you decide, treat it as final for a set period: “I’ll try this for three months, then review.” Gilbert and Ebert’s research suggests commitment helps you feel better about the choice. Delete the comparison tabs, return the extra items and stop researching.

7. Talk to yourself like a friend

Instead of “I always get this wrong,” ask: What would I say to a friend who made this choice with the information they had? Kindness reduces the fear that fuels doubt. See how to stop negative self-talk.

8. Build trust with small wins

Practise deciding quickly on small things, such as what to eat or which route to take, and notice that the world does not end. Keep a note of good decisions and how they turned out. See how to build self-confidence.

When doubt returns

Doubt will come back. Use this short script:

1. “I notice I’m second-guessing.”
2. “Did I decide with the information I had and my values?” If yes: “Then it was a reasonable decision.”
3. “Is there new information, or just anxiety?” If only anxiety, return to what you are doing.
4. “What is the next small step?” Do it.

A worked example

Priya accepted a job offer and cannot stop wondering whether she should have taken the other one.

1. Criteria: she wrote down her top three: growth, salary and commute. The chosen job met two clearly.
2. Good enough: she decides it meets her needs.
3. Limit: she stops reading about the other company.
4. Input: she talks to one mentor, then stops asking.
5. Reversibility: she reminds herself she can change jobs later if it does not work.
6. Commit: she decides to give it six months and then review.
7. Kindness: she tells herself she made a sound choice with what she knew.
8. Small wins: she notes what is going well each week.

The doubt fades because she stops feeding it.

Common mistakes

• Seeking perfect certainty. It does not exist.
• Asking everyone. More voices mean more doubt.
• Leaving options open indefinitely. It keeps the mind busy.
• Judging the decision by the outcome. Good decisions can have bad outcomes.
• Researching after deciding. It only feeds doubt.
• Beating yourself up. Self-criticism fuels second-guessing.

When to seek help

Consider talking to a therapist if:

• second-guessing is constant, distressing or interferes with work and relationships,
• you check and recheck things, or feel compelled to reassure yourself, which may point to anxiety or OCD,
• perfectionism or fear of mistakes is overwhelming,
• you avoid decisions altogether,
• you feel persistently anxious, low or hopeless,
• you have thoughts of harming yourself.

Cognitive behavioural therapy is effective for overthinking and anxiety. If you are in crisis, contact your local emergency number or, in the United States, call or text 988. See our disclaimer.

Frequently asked questions

Why do I second-guess everything?

Often because of fear of regret, perfectionism, anxiety, a tendency to maximize or a history of criticism.

How do I stop doubting my decisions?

Set criteria, aim for good enough, limit research and input, commit and talk to yourself kindly.

Is second-guessing a sign of anxiety?

It can be, especially if it is constant and distressing. It can also be a normal response to uncertainty.

What is the difference between a maximizer and a satisficer?

Maximizers try to find the best possible option; satisficers choose one that meets their criteria. Satisficers tend to be happier.

Does keeping options open make me happier?

Research suggests people are often happier with choices they cannot easily change.

How do I trust my gut?

Build trust through small decisions, notice what went well and check decisions against your values.

The bottom line

Second-guessing feels like care but usually keeps you stuck. Decide what matters, aim for good enough, set limits, ask for limited input, sort decisions by reversibility, commit, be kind to yourself and build trust through small wins. A decision you stand behind is worth more than one you endlessly reopen.
