6 quotes from self-made billionaires that will change how you think about money and success

"I can understand wanting to have millions of dollars, there's a certain freedom, meaningful freedom that comes with that. But once you get much beyond that, I have to tell you, it's the same hamburger."

"I thought back on my running career at Oregon. I'd competed with, and against, men far better, faster, more physically gifted. Many were future Olympians. And yet I'd trained myself to forget this unhappy fact. People reflexively assume that competition is always a good thing, that it always brings out the best in people, but that's only true of people who can forget the competition. The art of competing, I'd learned from track, was the art of forgetting, and I now reminded myself of that fact. You must forget your limits. You must forget your doubts, your pain, your past."
