PASSION COUNTS FOR A LOT The relentless intensity and total commitment that Mr. Jobs brought to his work, former colleagues and friends agree, had a simple explanation: he genuinely enjoyed what he did and found it worthwhile.

Andy Hertzfeld, a member of original Macintosh team who is now an engineer at Google, says: “The most important thing that I learned from Steve is to always follow your heart. He believed that the only way to do truly great work is to adore what you are doing.”

Mr. Jobs made a lot of money over the years, for himself and for Apple shareholders. But money never seemed to be his principal motivation. One day in the late 1990s, Mr. Jobs and I were walking near his home in Palo Alto. Internet stocks were getting bubbly at the time, and Mr. Jobs spoke of the proliferation of start-ups, with so many young entrepreneurs focused on an “exit strategy,” selling their companies for a quick and hefty profit. “It’s such a small ambition and sad really,” Mr. Jobs said. “They should want to build something, something that lasts.”

I don't intend to lionize the man in this post. He had plenty of faults, espcially with the way he handled his people, But there is a lot to learn from him and following the above four rules will help any Project Manager or Leader.
