i know a guy that should be one of these. he had 5 kids with a bipolar, and in his 60s he lives as if they don't exist. all day, every day in front of the computer. he's gotten 6 phds and written dozens of books, but no one cares. he basically has no friends, and no one respects him. lives alone. having kids didn't really change that.  i don't know what lesson to take from that, except that being good at something won't make people love you.
