Sometimes leadership is planting trees under whose shade you'll never sit. It may not happen fully till after I'm gone. But I know that the steps we're taking are the right steps.

We can't drive our SUVs and eat as much as we want and keep our homes on 72 degrees at all times... and then just expect that other countries are going to say OK. That's not leadership. That's not going to happen.

It's extremely hard for athletes to accept what's happened to them sometimes.

Security... it's simply the recognition that changes will take place and the knowledge that you're willing to deal with whatever happens.

For 13 to be unlucky would require there to be some kind of cosmic intelligence that counts things that humans count and that also makes certain things happen on certain dates or in certain places according to whether the number 13 'is involved' or not (whatever 'is involved' might mean).
