Generally I believe it's important to learn from your mistakes, which are inevitable. If you're learning and trying to do better, then regret should fade with time. I think the biggest mistake that I've made (that others might be helped to avoid by hearing about) was not to save money. I've had a lot of money flow through my hands over the course of my career as a programmer, yet I have very little to show for it, and I'm not getting any younger. Other than that, I mostly regret the times I've hurt people or not helped them but could have.
