It's very hard to answer that question... On the one hand I know that every good and bad decision I've made made me what I am and I wouldn't like to be somebody else than I actually am today. On the other hand there are, off course, things I would like to have done in a different way. But I think it's more important to draw the right conclusions from your mistakes instead of standing still. It's important do develop yourself and to not stop that from a certain age, although questioning yourself might sometimes be hard.
