Bill Gates' career trajectory:

- Access to a computer lab in high school, something not common at all in the '70s, was making small computer apps before his freshman year

- Attends Harvard, meets Paul Allen (working at Honeywell nearby) and Steve Ballmer (Math + Econ).

- Gets a chance to pitch Basic (or whatever it was) to a higher-up at IBM, since Gates' mom was on the board of United Way and could arrange an introduction.

There's a lot of stuff that goes unsaid in a LinkedIn profile.
