You always love playing in finals at any tournament. The grand slams and stuff like that are obviously the priorities but any titles go on your record.

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.

What if I start training my consciousness to know that it is a time and space traveller of unlimited proportions?

...You can't unlearn something, even if you want to. You know what you know.

Mindful living is a conscious way of living – noticing the beauty of life in every moment.

You will send me to the asylum for the truth, I know, I know!But before, Look within your skin, Hey, can you see me there?

There was a thing called Heaven; but all the same they used to drink enormous quantities of alcohol.

Right now the whole world seems to be going through a dark night of the soul.

The soul grows by subtraction, not addition.

I wonder what the difference is between love and lust.

If you seek nothing but the will of God, He will always put you in the right place at the right time.

I've spent several years now with my head down.
