Tennis has to become everything to you if you're going to make it to the top. You have to live it.
That's the key to success, isn't it? It has to be fun.
I lost my dad way too early and it was agonisingly awful. I missed him so much and I hated knowing that I could never again pick up the phone to tell him about my day.
You will never have great tennis champions from England because of the cold and dark, but most of all because people only care about the sport for two weeks a year, and then they're on to something else. There's just not a great love of the sport there.
Everybody has their story - at some point you have to say, 'This is who I am: Now it's up to me to become what I want to be.'
Did you know that Christmas Day is absolutely the best day to fly? It is. No crowded airports and crowded planes. I always flew to Australia. That's what Christmas was for me - a plane journey to the next tournament.
Life is not worth living if I cannot have pasta or bread again.
I have this terrible dark side to my personality, which playing tennis keeps at bay.
What I put in the stock market, I don't have to touch in my lifetime. I want to live off my bonds. I want to be that safe.
I am lucky to have advisers whom I trust.
I did realise more than ever, after the stabbing, that tennis is a business - a tough business.
I never really did Christmas before. Christmas Day? I mean - what's that? What's it all about? I was always flying on Christmas Day.
I would like to thank all my tennis fans who were there from Day One when I was No. 1, through my stabbing, and my comeback.
I've always been a very private person.
If I find the person that I love, it is because I love them, not because I will be dependent on them.
It doesn't matter who is playing or how old they are. I just worry about what I can control. It doesn't give me more or less motivation.
Madonna has total control over her life, and not many women have that.
People think I must have been so talented at an early age, but I don't know - was it talent or hard work? Who knows?
You have to want to play it all day, every day to get to the top.
If you look at tennis, the girls have become much more attractive; they wear makeup. In my generation, you were a tennis player. It wasn't like you had to look a certain way.
