I see PG's quote as true, but hard to swallow. The truth is you do have to be the right kind of person to be successful (in this context, successful at startups). A person born with severe retardation or another mental incapacity is not the right kind of person to be successful at startups. The right kind of person has the genetic makeup, personality type, upbringing and/or access to resources to become successful. Not everyone has this and that's okay. And also, you (usually) don't know if you're the right kind of person until you try. So if you want to, try and keep trying until you don't want to anymore.
