Yeah, but if you check they tend to have two things, one being a level of drive and determination coupled with an almost ruthless ambition, the other is they come from money. Sure Richard Branson did not go to college, but he did go the best schools in England including Stowe*, which pretty much gave him the equivalent of a college education by the end of high school. His grandfather the Right Honourable Sir George Arthur Harwin Branson, was a judge of the High Court of Justice and a Privy Councillor - and in England that stuff matters, a lot. Yeah, Bill Gates never graduated college, he dropped out, but he dropped out of Harvard, which means he was good enough to get in, and came from a family rich enough to pay for it.**
* - Stowe is also where Roger Hodgson of Supertramp went to school, and is pretty much the basis for The Logical Song.
** - his father was a prominent lawyer, his mother served on the board of directors for First Interstate BancSystem and the United Way, and her father, J. W. Maxwell, was a national bank president.
