If you're early on in your career and they give you a choice between a great mentor or higher pay, take the mentor every time. It's not even close. And don't even think about leaving that mentor until your learning curve peaks.

With my business, the way you make big money is you find a great management team and a good concept, and you stick to it, and you add to it over time. In philanthropy, there was more this idea that once an idea was formulated, you moved along.

I love being around kids. I couldn't figure out why all these 70-year-olds wanted to hang out with me when I was 27. Now I understand, and I'm trying to steal their energy from them like they stole from me at the time.

All in all, I don't think robots and greater automation can bring about a utopian world as I imagined it would as a kid 50 years ago.

I don't put Tesla in the Amazon category. They have not proved to me that, as a financial model and an economic model, it is going to work.

I've always loved to play games, and face it: investing is one big game. You need to be decisive, open-minded, flexible and competitive.

Good debt growth is when you borrow money, and it goes into the real economy. You do capital spending. You build businesses.

Carried interest... you're making money on somebody else's capital. It's not on your own. If that's not income, I don't know what is.

You can be far more aggressive when you're making good profits.

Whenever I see a stock market explode, six to 12 months later you are in a full blown recovery.

I love Amazon.

In my experience, the more successful an idea is, the easier it is to fund it. In philanthropy, it's almost harder.
