I always looked ahead.

I love hiking in the mountains in Aspen. Breathing the clean, fresh air is great. Plus, it gives me a cardiovascular workout and firms my legs.

If you're a champion, you have to have it in your heart. You can have the greatest coaches in the world, all the opportunities to play, and the greatest equipment, but if you don't have it inside, you're not going to make it. On the other hand, if you don't have any of those luxuries but you have heart and courage and the guts to go out there and grind it out, then you'll make it.

I can definitely say the same thing [discussing Steffi Graf's claim that she had played against at least one top player who used steroids]. Steroids can really make a difference, physically and mentally. I'd be really disappointed if I had been ranked No. 2 behind someone who took steroids.

I still have this image: I can't be controversial, I can't say things.

I've had a lot of fear in my life, from fear of flying to fear of making a speech in front of a lot of people.

If you can react the same way to winning and losing, that's a big accomplishment.
