Why'd you leave the match, huh?

That's when you've got to grit your teeth and hang in there and try and find a way to win when you're not playing your best tennis - that's what I can be proud of

Even when I was No. 1 in the world, I was taking it one match at a time. I never was a player to look too far ahead, the way draws can pan out.

When I go out to play, I still believe I'm as good as anyone out there. I don't have to prove anyone wrong. I know what I've done and how well I can play.

I'm fortunate: I can play as long as I want to play. There's no coach or trainer who is going to say to me that I'm dropped or sacked, it's time to move on. I can play as long as I want to play.

Matches are won and lost so many times in the locker room.

When I was a kid in Adelaide, I dreamed of becoming No. 1 in the world, winning a grand slam and the Davis Cup for Australia.

I was lucky enough to win the Davis Cup in my first year in 1999. I won my first slam at the U.S. Open in 2001 and became world No. 1 later that year. By the age of 20, I'd done it all.

I'm not a guy who needs to read motivation books.

Everyone has to call 'time' at some stage.

That's what you do all the hard work for, to play in situations that put your body through gruelling times. If you're not up to it, pull out.

A new position of responsibility will usually show a man to be a far stronger creature than was supposed.

Humility is as good for the soul as it is for the memory

It's one thing to make financial aid available to students so they can attend college. It's another thing to design forms that students can actually fill out.

I do condition my hair with honey and beer. I smell like the bottom of a beer barrel for days afterwards, but it's very good for the hair.

I live by statistics, so if look at U.S. Census statistics regarding families making over $100,000 dollars a year, 93% of them have broadband internet at home.

For a society as abundant and as blessed as ours, to have as many disadvantaged children as we have does not bode well for our long-term economic future.

In war, the general alone can judge of certain arrangements. It depends on him alone to conquer difficulties by his own superior talents and resolution.

I believe in telling the truth.

The great thing about America is you can live according to your faith. If you're faith says don't use birth control then you don't use it.

The only instrument I can play is piano. Whenever I make songs at home, I play the piano and make them on the piano.
