NATO is built on security, but it's also built on values.

I'm a strong believer that you have to have an equal opportunity to fail and to try things that are hard. I always tell my students, "Don't just take things that are easy for you. If you're really good at math, don't take just math. Take classes that make you write. If you're a really great writer, but bad at math, take math and make yourself work your way through it."

What I tell student athletes is first of all, you've made good choices this far in order to be able to be in college and to be an athlete. Keep making good choices.

I think our dependence on foreign oil is a real problem, potential Achilles heel, and we have to do something about it.

You do have to keep in mind as you're going through extraordinarily difficult circumstances, that if you stay true, true to your values, if you stay true to your principles, if you believe in these values, then you can work in that context to right policies that may not be working.

I don't like anything that's "just an escape." To me the best part of golf is that, unlike my tennis game, I can actually get better. I've probably reached my plateau in tennis, but in golf I have a lot of room for improvement. I really enjoy working on my game. I like practicing. I chart my rounds.

Life is full of surprises and and serendipity. Being open to unexpected turns in the road is an important part of success. If you try to plan every step, you may miss those wonderful twists and turns. Just find your next adventure-do it well, enjoy it-and then, not now, think about what comes next.
