i basically never had to work (EU privilege + luck of being born the skill of knowing how to sell to people well) and only worked on stuff that i enjoyed and not a lot of hours (and that turned into millions fast) and my 20s/30s flew like months instead of years and didn't have the intensity of my teen years. I think it's because despite technically travelling and living in different countries a lot, going to a new place is not really a new experience after you visit 7 very different ones. The same with women and a lot of other experiences. Having kids was the only think that surprised me. Making money got old fast (i mean trying to get to the "next" level)
