Leadership is unlocking people's potential to become better.

I always thought the objective of basketball was to get the maximum amount of movement to get the easiest shot, closest to the basket. With the three-point rule, the whole strategy changes, and you make a move and then throw it 30 feet out, where somebody takes a standing jump shot.

Look, I have no qualms about having played basketball. The game has done so much for me. Look at the places I've been, for one thing.

For much of my career I had no authentic political voice. I had been campaigning all over the country not to change the world or shake up my audiences but to please the roomful of people to whom I was speaking... As a result, my words rarely had the ring of truth to the nonpolitical observer.

It all went wrong with football, the thing I loved most of all, and from there, my life slowly fell apart.

Purposefully exposing young people to increased risks of major brain problems - even death - for sport is surely even more ethically complicated than sending young people into this same neurological danger zone as soldiers.

I know my game pretty well, and that is the secret to success in most sports.

I just go out there every game and try to be the best I can be for our team.
