Every Olympics is something special. If you're fortunate enough to play for your country - there's just so much energy. It's truly amazing.

I knew my destiny was to be in the winner's circle. There were times along the way where I didn't make it there. But I felt my destiny was definitely to win big titles, win lots of titles.

The naysayers, they don't mean a thing.

Serena and I, we don't have anything to prove ... we still set a very high standard.

Tennis is mostly mental. Of course, you must have a lot of physical skill, but you can't play tennis well and not be a good thinker. You win or lose the match before you even go out there.

I know it's not the most important thing for me to win the most grand slams and be remembered in this world. I certainly don't have to win satellite tournaments here there and everywhere, I don't have to win at all. Although I do want to.

Sometimes, when there's a video montage. I'm thinking, 'That's my life. Oh, my God, I did that.' Yeah, it's amazing.
