Leadership is about empowering others to achieve things they did not think possible.

I was always curious why certain marketing worked and some marketing did not.

Curiosity is essential for progress. Only when we look to worlds beyond our own can we really know if there's room for improvement.

The quality of a leader cannot be judged by the answers he gives, but by the questions he asks.

I don't care about convincing the people who think I'm naive or an idiot. I'm interested in how do I inspire the people who are open-minded that there's a different way of seeing the world.

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

My challenge is to make sure the things I say and the things I do remain consistent for as often and as long as possible. My why is to inspire people to do the things that inspire them so that together we can change our world. That's why I wake up every single day. I'm agnostic to the form it takes: I teach, I write, I speak, I advise.
