The water bottle on the new desk

An illustrative example. Three weeks into her new job, Hannah still kept the water bottle from her old company on her desk, the faded logo turned toward her keyboard. Every time she reached for it, the same question surfaced: Why did I leave? The new role paid more and the commute was shorter, but the team was quieter, the onboarding was patchy, and her old manager had just posted a photo of the office party she would have been at.

Nothing dramatic had gone wrong. Yet the decision she had thought about for two months now felt like something she had to defend to herself every morning. If you have ever signed a lease, accepted an offer, sold a car or said no to an opportunity and then found yourself rerunning the choice for weeks, this guide is for you. It covers what decision regret is, why a finished choice keeps reopening, and how to stop regretting a decision without pretending you feel nothing.

Regret that teaches versus regret that loops

Regret is the painful sense that things would be better if you had chosen differently. In small doses it is useful. It points to something you value, and it can sharpen the next decision: you notice that you underestimated how much a team matters to you, or that you rushed because of a deadline.

The trouble starts when regret stops producing information and starts repeating itself. You replay the same moment, picture the same alternative life, and arrive at the same conclusion, without learning anything new. Psychologists describe this kind of repetitive, unproductive thinking as rumination. Researchers such as Susan Nolen-Hoeksema and colleagues have described how rumination keeps attention fixed on distress and can make practical problem solving harder rather than easier. The goal of this article is not to erase regret. It is to help you take the lesson and leave the loop.

Why a finished choice keeps reopening

A few well-studied patterns help explain why a decision can feel unfinished long after you made it.

Actions sting sooner. In their 1995 review on the experience of regret, Thomas Gilovich and Victoria Medvec described a time pattern: in the short term, people tend to regret things they did more than things they did not do, while over the long run regrets about missed chances tend to loom larger. A recent, active choice such as quitting a job sits squarely in the window where regret about action feels sharpest. That is worth knowing, because it suggests some of the early sting may fade on its own.

An open door makes it harder to settle. Daniel Gilbert and Jane Ebert ran experiments in which some people could still swap a choice they had made and others could not. Most people preferred to keep the option open, yet those whose choice was final tended to like their outcome more. When a decision still feels reversible, the mind keeps reviewing it instead of making peace with it.

Searching for the best keeps the comparison alive. Barry Schwartz and colleagues distinguished "maximizers", who try to find the best possible option, from "satisficers", who look for one that meets their standards. In their surveys, maximizers reported more regret and less satisfaction. If you tend to measure every choice against the perfect version, a good decision can still feel like a loss.

Moments that tend to set it off

• The first rough patch. A bad day in the new flat, job or city feels like proof that you chose wrong.

• News from the road not taken. A former colleague's promotion, a photo of the house you did not buy, a price drop on the car you sold.

• Someone else's opinion. A relative asks, "Are you sure that was wise?" and the old debate restarts.

• Tiredness and quiet moments. Regret often grows louder during a commute, in the shower or when you finally sit down in the evening.

• Money leaving your account. Rent, fees or a first payment make the cost of the decision concrete.

What keeps the wound open

Some habits feel like problem solving but mostly feed the loop. Checking the alternative, for example by scrolling the listing of the house you passed on, keeps the imagined better life vivid. Comparing your real, messy outcome to an imagined, flawless one is never a fair fight. Polling friends until someone agrees you made a mistake gives you a verdict but not a plan. And keeping one foot out of the door, telling yourself you could always go back, makes it hard to invest fully in the path you are actually on.

Judging the choice only by how things turned out is another trap. A good decision can lead to a bad result through bad luck, and a careless one can work out fine. When you grade yourself purely on outcomes, every setback becomes evidence against you.

Judge the decision by what you knew then

The first technique is to separate the decision from the outcome. Take a sheet of paper or a note on your phone and write a short "decision record" in the past tense:

• What did I know at the time?

• What options did I realistically have?

• What was I trying to protect or gain?

• What did I not know, and could I reasonably have found it out?

Most people discover that their past self made a sensible choice with the information available. Regret often borrows knowledge you only have now. If you find a genuine gap, such as skipping a conversation you could have had, write that down too. That is the lesson, and it is far smaller than the vague verdict "I ruined everything".

Decide whether to close the door or open it properly

The second technique tackles the half-open door. Ask honestly: is this decision still reversible, and would reversing it actually serve what I care about now? There are only two useful answers.

If reversing is not possible or not worth it, close the door on purpose. Tell yourself, in plain words, "This choice is made. I am now working on making it go well." You might even mark the moment, for example by putting the old water bottle in a cupboard. If reversing is possible and might be worth it, stop debating it in your head and reopen it properly: set a review date a few weeks away, list what would need to be true for you to change course, and gather real information until then. Either way, the decision leaves the endless middle ground where most regret lives.

Take the lesson, then put the rest down

The third technique is to step back. Ethan Kross and Özlem Ayduk have described how "self-distancing", reflecting on a painful experience as if from the outside, can help people make sense of it with less emotional reactivity than replaying it in the first person. Try writing about the decision using your own name, or ask what you would say to a friend who made the same choice for the same reasons.

Then reduce everything to one sentence that begins "Next time, I will...". For example: "Next time, I will ask to meet the team before accepting an offer." Once the lesson has a home, you have permission to stop rereading the case. When the thought returns, you can answer it with that sentence rather than restarting the trial. Our guide on turning a worry into a concrete next step explores this move in more detail.

Hannah works through it: an illustrative example

Back to Hannah, whose situation is invented for this article. On a Sunday afternoon she writes her decision record. At the time, she knew the old job had stalled: no promotion path, a manager who kept postponing her review, and a ninety-minute commute. She wanted growth and her evenings back. What she did not know was how slow onboarding would be or how quiet the new team felt in the first weeks. Could she have found that out? Partly. She could have asked to meet a future colleague.

Next, the door question. Going back is technically possible, since her old manager said "you're always welcome", but nothing that made her leave has changed. She decides to close the door and sets one review date three months out, to check honestly whether the new job meets the needs she listed. Until then, she stops treating each slow afternoon as a verdict.

Finally, the lesson: "Next time, I will ask to speak with someone on the team before I accept." She moves the water bottle into her bag for the gym, books a coffee with a colleague on Tuesday, and notices that the question "Why did I leave?" still appears, but more briefly, and now has an answer.

Missteps that keep regret alive

• Trying to stop the feeling by force. Telling yourself "don't think about it" usually brings it back. Acknowledge it and redirect.

• Reopening the decision every day. Without a set review date, every mood becomes a referendum.

• Collecting opinions. More voices rarely add new facts after the fact.

• Only counting the losses. List what the decision gave you, too: time, money, freedom, a clean break.

• Turning a lesson into self-punishment. "I should have asked more questions" is useful. "I always get things wrong" is not.

A seven-day plan for a decision you keep rerunning

1. Day 1: Write the decision record: what you knew, your options, your goals, what you could not know.

2. Day 2: List three things the decision has already given you, however small.

3. Day 3: Answer the door question. Close it deliberately, or set a review date and a clear test for changing course.

4. Day 4: Reduce the lesson to one "Next time, I will..." sentence.

5. Day 5: Remove one trigger, such as unfollowing the old listing or muting a group chat for a while.

6. Day 6: Take one action that invests in the path you chose.

7. Day 7: Notice how often the regret appeared this week compared with the first day. Keep the review date; drop the daily trial.

Questions readers often ask

Is it normal to regret a big decision even when it was the right one?

Yes. Any real choice involves giving something up, and missing what you gave up is part of choosing. Early regret after a big change is common and does not, on its own, mean the decision was wrong.

How long does regret after a decision usually last?

There is no fixed timeline. Research on the timing of regret suggests the sharp sting of a recent action often softens with time, especially once you stop reopening the choice. If it is not easing after several weeks, a written review can help you see whether there is a real problem to solve.

Should I reverse a decision I regret?

Sometimes. If new facts show the choice is clearly not working and reversing is realistic, changing course can be wise. Decide that at a set time, against criteria you wrote down, not in the middle of a bad evening. Our article on how to stop second-guessing yourself may help.

What if my decision affected other people?

Then the lesson may include a conversation or an apology. Do that once, sincerely. Repairing what you can is useful; carrying endless guilt helps no one.

When regret needs more than a technique

If regret or overthinking is seriously affecting your sleep, work or relationships, or if you ever have thoughts of harming yourself, please speak to a doctor or a licensed mental health professional. In the US you can call or text 988, and in the UK you can call Samaritans on 116 123, at any time.

Living with the choice you made

You cannot go back and make the decision with today's knowledge, and nobody else can either. What you can do is judge your past self fairly, decide whether the door is closed or open, keep one clear lesson and put the rest down. The choice becomes part of your story rather than a case you keep retrying. Start with the decision record today; it takes about ten minutes.

Try a guided version with unLooper

If you would like some structure, unLooper, an iPhone app made by the publisher of this site, has two tools that fit this situation. The Overthinking Breaker is a short guided session of about three minutes: you capture the regretful thought, separate fact from fear, look for other angles and pick one small next step. If you are seriously considering reversing a choice, the "Decide for me" workspace lets you weigh the options against your own priorities, with an optional AI review of the trade-offs.

Using it is entirely optional. It is a self-reflection tool, not therapy, and you stay in charge of every decision. You can find it here: unLooper on the App Store.
