Has there ever been a successful business that came about by a guy thinking up a most excellent idea in entrepreneurship class (???) then carefully selecting the proper co-founders and continuing to make ideal decisions until success?

In most stories I've heard or read about successful businesses, the pattern was more like, a bunch of freaks got together, massively screwed up half the time, made a few lucky moves, and kept persevering until eventual success.

I guess what I'm trying to say... is... this seems like the wrong attitude:

"I don't want to jump into this on a high of excitement with people that perhaps might not be fit for it."

If the people aren't a good fit, just dump them and move on. Look at Zuckerburg with Facebook. He worked on Facebook-like ideas three times with various groups of uncommitted people until he finally got it right.
