Good content, but my favorite part of the article is the anecdote about how Paul started at Google. Putting yourself in a place where you have the opportunity to be lucky makes up some percentage of the total likelihood of being extremely successful (yes, I consider Paul extremely successful along many axes), but I think a much larger portion of this equation is actually being lucky. I guess if you iterate over and over again, by say joining startups repeatedly, eventually most people get lucky in some way. The magnitude of that success however, is certainly highly variant.
