There's also an aspect of optimism to it, I think, not just naivete. I have enjoyed the startups that I've worked at, but I feel very out-of-place when I'm around many serial entrepreneurs because they seem to latch on to an idea and think it has extreme potential far more easily than I do. If you're optimistic and actually ENJOY being motivated by potential more than a paycheck, you'd probably trade salary for it. Just not who I am, nor a bet I think is sensible. But each to his own.
