Regret has a way of looping. You replay the decision, rehearse the better version of yourself who chose differently, and feel the same sting all over again. It can sit quietly for years or surface at three in the morning, and it tends to grow heaviest in exactly the parts of life we care about most.
The good news, borne out by decades of psychology research, is that regret is not a verdict on your character. It is information — and there are concrete, evidence-based ways to work with it so it stops running your life and starts pointing you somewhere useful.
What regret actually is (and why it hurts)
Regret is what psychologists call a counterfactual emotion: it lives in the gap between what happened and the “if only” version you can imagine instead. We feel it most sharply when the better outcome seems close — when we can almost touch the road not taken.
That is why regret is not a sign that something is wrong with you. It is a sign that you are capable of imagining better, and that you care about the outcome. The leading researcher in the field, psychologist Neal Roese, has long argued that regret is among the most useful negative emotions precisely because of this: it helps us make sense of what went wrong, draw out a lesson, and approach future opportunities differently (Roese, author of If Only).
The trouble is that regret only pays off when we let it inform us. Left to loop, it just hurts. The work is in turning the loop into a signal.
Why we regret most where we have the most room to grow
One of the most quietly reassuring findings in the research is about where regret clusters. In a landmark analysis of regret studies, Roese and Amy Summerville found that people’s biggest life regrets concentrate in the domains where they perceive the greatest opportunity for change — in descending order: education, career, romance, parenting, the self, and leisure. Their conclusion was striking: “people’s biggest regrets are a reflection of where in life they see their largest opportunities” (Roese & Summerville, 2005).
Read that again, because it reframes everything. The thing you regret most is usually the thing you still believe could be different. Regret marks the live wires — the areas where you sense room to grow. So instead of asking “why can’t I let this go?”, a more useful question is: what does this regret think is still possible?
The regret most people carry longest
There is a well-documented pattern in how regret ages. In the short term, we tend to regret the things we did — the embarrassing email, the impulsive purchase, the words we wish we could take back. But over the long run, the regrets that stay with us are mostly the things we didn’t do: the chance not taken, the conversation never had, the version of life we talked ourselves out of.
Thomas Gilovich and Victoria Medvec first mapped this in 1994, and the explanation is human and a little poignant: regrets of inaction don’t fade the way regrets of action do, partly because we romanticize the road not taken, and partly because the fears that once stopped us seem far less convincing in hindsight (Gilovich & Medvec, 1994). Later replications found the same temporal pattern, with somewhat weaker effects (Towers et al., 2022).
Two practical things follow. First, when you are deciding now, your future self will likely forgive a brave attempt that didn’t pan out far more easily than a chance you never took — useful to know when fear of regret is the very thing stalling you. Second, when an old regret of inaction still aches, the honest question isn’t “why didn’t I?” but “is the door truly closed, or am I just assuming it is?”
How to overcome regret: five evidence-based moves
None of these “erase” regret, and you wouldn’t want them to — an emotion this informative is worth keeping. They change your relationship to it, so it teaches instead of torments.
1. Meet it with self-compassion, not a verdict
The instinct is to either punish yourself (“how could I have been so stupid?”) or shove the feeling away. Research suggests a third path works better. Across three studies, Jia Wei Zhang and Serena Chen found that bringing self-compassion to a regret led to greater personal improvement — and that the effect ran specifically through acceptance. People who could stay in contact with the regret without self-attack were the ones who actually grew from it. Notably, this wasn’t just high self-esteem in disguise; self-compassion did something self-esteem didn’t (Zhang & Chen, 2016).
In practice: talk to yourself the way you’d talk to a good friend who made the same call with the same information they had at the time. Acceptance isn’t approval — it’s the doorway to learning. If self-criticism is your default setting, our guide to self-forgiveness walks through this in more depth.
2. Mine the regret for the actual lesson
Regret’s whole value is its informational payload. Make it explicit. Ask: what exactly do I wish I’d known, valued, or prioritized? What does this tell me about what matters to me now? A regret about a career you didn’t pursue isn’t really about the past — it’s data about what you want your next chapter to weigh more heavily.
3. Separate the decision from the outcome
A good decision can lead to a bad outcome, and a reckless one can get lucky. Judging your past self only by how things turned out is a quiet form of hindsight bias. Ask instead: given what I knew and felt at the time, was that a reasonable call? Usually it was. That reframe is the heart of how cognitive behavioural therapy loosens the grip of “what if” — see spotting the cognitive distortions that make regret feel like fact.
4. Convert “if only” into “next time”
Counterfactual thinking — the “what might have been” — causes short-term pain but carries a long-term motivational benefit, if you point it forward. Turn each backward “if only I had…” into a forward, specific “next time I will…”. This is the move that changes regret from a loop into a plan. If you find yourself stuck in the rumination instead of the planning, our guide to quieting an overthinking mind can help.
5. Take one concrete step toward what the regret points at
Because lasting regret skews toward inaction, the most reliable antidote is a small action in the direction the regret is pointing. Not a life overhaul — one email, one conversation, one enrolment, one honest sentence said out loud. Action settles regret in a way rumination never can. If even the first step feels impossible, how to get unstuck breaks it down further.
What about the fear of regret before you decide?
Sometimes regret isn’t about the past at all — it’s a future you’re trying to avoid, and it freezes you at the crossroads. “What if I choose wrong?” becomes a reason to choose nothing, which, of course, is itself a choice.
The research offers a quiet kind of permission here. Since the regrets that last longest tend to be the chances not taken, the decision most likely to age badly is usually the one you avoid out of fear. You don’t need certainty to choose well — you need a decision you can stand behind given what you know today, and the self-compassion to forgive an honest attempt that doesn’t land. If you tend to spiral over choices, a simple decision-making framework can give the fear something steadier to hold onto.
When regret is heavier than this
Everyday regret — the missed opportunity, the choice you’d remake — is a normal, even useful part of a thoughtful life. But sometimes regret hardens into persistent rumination, self-blame that won’t lift, or a low mood that colours everything. If a regret has stopped feeling like a lesson and started feeling like a weight you can’t put down, that’s worth taking seriously, and a qualified therapist or your doctor can help you work through it.
For most of us, though, the path through regret looks like this: feel it, learn from it, forgive yourself, and let it point you toward the next brave, ordinary step. Talking it through can make that path clearer — whether with someone you trust, a professional, or aidx.ai, which offers AI coaching and therapy for moments exactly like this. Regret is, in the end, your own mind telling you that you still have room to grow. That’s not a bad thing to hear.
