Gates said on his speech at the University of Washington, on October 27, 2011:
I didn’t start out with the dream of being super-rich. And even after we started Microsoft, and the guys who ran Intel—Gordon Moore and those guys—were billionaires, I was like, ‘Wow, that must be strange.’ And so—it is, it’s quite strange,” he said to laughs from the crowd.
“But I think most people who’ve done well have sort of found something that they just are kind of nuts about doing. And then they figure out a system to hire their friends to do it with them. And if it’s an area of great impact, then sometimes you get financial independence,” Gates said.
“But wealth above a certain level, really, it’s a responsibility that then you’re going have to either, a.) leave it to your children, which may or may not be good for them, or b.) try to be smart about giving it away.
“So I can understand wanting to have millions of dollars, because there’s meaningful freedom that comes with that. But once you get much beyond that—you know, I have to tell you, it’s the same hamburger. Dick’s has not raised their prices enough,” Gates said to laughs. “But, you know, being ambitious is good. You just have to pick what you enjoy doing.”
I think these words are true today, and it will still be true for the longest time. That's how greatest company -- the likes of Apple, Microsoft, Intel, Ford, Sony, IBM -- is being built. Passion, innovation and imagination drives it since they were small. Greed never did.
