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.

So I find that teaching and the students keep life going, and I would never accept any position in which somebody has invented a happy solution for me where I don’t have to teach.  Never.

The friends with whom I sat on graduation day have been my friends for life. They are my children’s godparents, the people to whom I’ve been able to turn in times of trouble, people who have been kind enough not to sue me when I took their names for Death Eaters.

The desk helps, now that I have it. I’ve stacked piles of books that I love on it to act as talismans. They help, too. The desk makes me feel like I’m going to work, even though work is located in a cramped but bright corner of my living room. […] I used to think of myself as someone with a great deal of discipline, but I lost it in the air somewhere over the Rocky Mountains. Now, instead of discipline, I have a desk, and every day that I sit at it I dig a little deeper.

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.
