I believe that our "success trajectory" is something like 10-20% our own choices and 80-90% pedigree / where we start from. And probably some percentage of "other luck." So I don't really think too hard about doing it over because I don't feel like I've made many really bad decisions. I've gotten about as far as I could have reasonably expected, given being born to a family of school teachers living in a rural middle of nowhere, where success meant getting a decent job at the local mill. No do-over would make my father a rich, well-connected businessman. No do-over would get me into Phillips Exeter Academy as a high schooler and then Harvard or Yale. No do-over would land me in Goldman Sachs post-graduation. So I really don't dwell on what might have been. If I could go way farther back in time and bend my entire family tree's trajectory such that I started out on 3rd base, that would be a different story.
