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

I go into every meeting, into every room and for every speech understanding the standard deviation, the Bell Curve. I know there are about 10-15 percent of people in the room, who say, "I've been trying to say this for years. Finally. I agree. Yes, yes, yes." I know there are about 15 percent of the people in the room who think I'm an idiot, who think I don't know what I'm talking about, who think I'm naive or I have oversimplified everything. The majority who are open to the ideal.
