There was an article [0] shared here last month that I found useful for weighing the relative importance of ideas vs execution.
IMO, there are many many million-dollar-ideas (million with an m, not billion) out there, that are enough to make a bootstrap startup out of.
Many people see these ideas, but don't develop them because the problems are "body-building hard" instead of "ideas hard". Working 9-5 at $BIG_CO is neither kind of hard most of the time, and most people prefer that.
