We need to have mentors. I think I've always been pretty shameless about seeking out people much smarter and much more experienced than me from the very beginning. Michael Seibel and other people. And the more successful I got, the more leaders I started seeking out, whether it was investors, or Sheryl Sandberg at Facebook, or I got the opportunity to spend time with Warren Buffett and he became a close mentor of mine.

When I decided to sell my company, I already had enough. I live simply. I don’t own a house, a car, or even a TV. The less I own, the happier I am. The lack of stuff gives me the priceless freedom to live anywhere anytime. So I didn’t need or even want the money from the sale of the company. I just wanted to make sure I had enough for a simple comfortable life. The rest should go to music education, since that’s what made such a difference in my life.

They win the respect, the deserved trust, of the people they deal with, and there is huge pleasure in life to be obtained from getting deserved trust. And so the way to get it is to deliver what you’d want to buy if the circumstances were reversed.

Our business everyday is to make money for people. And I take it as seriously as doctors who are trying to cure cancer, because by giving people financial freedom, we allow them to do great things in their lives - from retire to send their kids to college, to buy their first house, to fund a business that they might want to start.

Never give up your passion for learning. And zoom out of your field before you zoom in. Some of my very best business insights have come from reading around subjects. They have come from approaching questions at a strange angle, from thinking about them from a different point of view. A lot of the knowledge that has really given me an edge in business has come from history, psychology, even chemistry. Connecting seemingly unconnected dots is what has served me well.

In order to grasp every opportunity, you cannot — you must not — decide your "career path" in advance. Don't have a job fixed in your sights and work backwards — it can be the road to disappointment because you risk passing up opportunities that might take you "off-course."
