When you're a catalyst for change, you make enemies - and I'm proud of the ones I've got.

I'm not looking for a legacy, and you'll never shut up the critics. I've been around 50 years. When you're a catalyst for change, you make enemies - and I'm proud of the ones I've got.

I'm a catalyst for change. You can't be an outsider and be successful over 30 years without leaving a certain amount of scar tissue around the place.

I would like to be remembered, if I am remembered at all, as being a catalyst for change in the world, change for good.

In motivating people, you've got to engage their minds and their hearts. I motivate people, I hope, by example - and perhaps by excitement, by having productive ideas to make others feel involved.

This is a time of fundamental change.
