I know one person my age (or younger) who is more successful than me - in that, he makes more than I make, while living in the same city. I never really envied him, because I recognize that life has a huge random element to it, and he just got more lucky than me (landed in a specialty which happened to pay more than mine). Perhaps it would be different if a lot or even majority of people I know would be more "successful" than me.
