For the history Steve Jobs, which includes MAC OS X, watch http://www.youtube.com/watch?v=0MwD-TZ6r9Y.
Another cool point about Steve Job's job history, at 23, he had over one million dollars, at 24, over ten million, at 25, over one hundred million. That certainly allowed a lot of freedom to continue to try new things such as buy a graphics image company from Lucas Films which he renamed Pixar.
