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.

Thank goodness, too. Because that was a long-term investment in myself.

Diversifying means going abroad…Be in another culture, speak a different language, see how other people think. Leave and then come back.

we should invest the majority of our wealth the same way we are investing the majority of our time- by helping to improve people's lives.

For me, school was probably the most traumatising and most difficult part of my life. I already was being bullied at the age of six. I think at the time, (at) that particular school, I was probably one of three kids of colour and just bigger, stronger, bullying kids were throwing me around a lot of the time.
