I also found this interesting. My father has run his own business full time for 20 years, and did it part time before that. I think that's a big reason I started my own business ~2000, though it certainly was not a startup as we think of the term. A lot of the reluctance to do a startup is simply fear of the unknown, or thinking there's some "secret sauce" that one doesn't know. Like most things in life that don't have a prospect of being immediately fatal, often the best advice is "Just do it"
