As an adult out of school for 20 + years, how has your life turned out compared to the lives of those you used to go to school with?

I am not asking from a competitive point of view, but from what you have found out are most of you on the same level? Have there been many great overachievers, anyone who has become brilliant or famous, any drama stories, premature deaths and even any strange twists? By strange twists, I mean people whom you were expecting to shine finally ended up messing up, and people who were a mess back then turned out to be successful.
Have most cruised smoothly or have you heard awful tales of struggle?
