We learn most not from all of the things that go right. We learn most when everything goes wrong.

I have been inspired by Martin Luther King and how he inspired a movement. I have learned that a cause must be organic; if it is to have an impact it must belong to those who join the movement and not those who lead it.

Vision is the ability to talk about the future with such clarity it is as if we are talking about the past.

I cannot tell you how long it takes for your exercise to work. If you haven't seen any results in a year or six months you're doing something wrong.

What's important to me is that I put messages out, whether it's a TED talk, whether it's a book.

We can't all be good at everything. This is partly the logic behind having a team in the first place, so each role can be filled with the person best suited for that role and together, every job and every strength is covered.

More information is always better than less. When people know the reason things are happening, even if it's bad news, they can adjust their expectations and react accordingly. Keeping people in the dark only serves to stir negative emotions.
