I wholeheartedly second this. Even though I quit a high paying job which I could work any hours I wanted to and had full autonomy, I've known owning my own business was something in the makeup of my person for a long time now. I think people like me are the exception, though, and that a lot of the "coolness" of owning your own startup puts social pressure on people to do something they might not even be suited for. I don't think the prototypical engineer is truly suited for startup life, and neither is the prototypical business guy. Both of those jobs need to typically work within an established framework, while a lot of startup businesses are about busting out of a framework or completely inventing your own. There's absolutely nothing wrong with not being a millionaire/billionaire. Yes, you can't have your own island, design and commission your own uber-boat, or provide flu shots to an entire city, but a lot of people seem to be able to find happiness without those things. Personally, my end-goal regardless of success is to teach a high school web/game programming course, or whatever is popular to learn at the time. The only reason I'm not doing that right now, is that I'm curious to know whether or not the drive inside me to build things is a part of my ego or my destiny.
