I'm 23.
I don't like people my age, including myself.
I'm 29. It doesn't change. I've no problem with the average 29-year-old (or the average 23-year-old) but the types of people who do well, young, in VC-istan are pretty irritating.
The types who do well at older ages aren't much better.
For people, I prefer Wall Street. No, I'm not kidding. The work isn't as interesting, but the people are more decent.
