When things don't go as planned, people imagine how it could have been different. Bronze medalists feel happier than silver medalists because they think about finishing fourth instead, while silver medalists regret not winning gold. Regret is painful but useful if you use it to do better next time.
Why are third-place finishers happier than second-place finishers? It's called counterfactual thinking, imagining what could have happened. Bronze medalists think, at least I didn't come in fourth. That's a downward counterfactual, imagining something worse. Silver medalists think, if only I had pushed a little harder. That's an upward counterfactual, imagining something better. Regret is an upward counterfactual. It hurts, but done right, it can help. Because by imagining how things could have gone better, We can do better next time. So the next time you feel regret and think, if only, don't ignore the feeling and don't beat yourself up over it. Use the feeling to fuel your next move.
