But these guys learn so fast now, they sort of soak up the information, they're fearless. Those are the guys who learn from their mistakes and come back strong the next time.
Things slow down, the ball seems a lot bigger and you feel like you have more time. Everything computes - you have options, but you always take the right one.
I think it was the right time for me to retire because nowadays tennis is too incredibly fast and you can say that my style tennis went out of fashion.
I wasn't a perfect thing at 17. I didn't have confidence. I was hunched over and real embarrassed, and I didn't want to be in the limelight. But it changed over time.
The serve, I think, is the most difficult, you know, in terms of coordination, because you got the two arms going, and you got to toss it up at the right time so.
My heart is in South Africa, through my mum. My mum being from here, me spending a lot of time here as well, I feel most connected to this part of the world.
It's more a tennis problem than a mental problem. The transition is difficult. It depends how much time you have. Playing on grass can sometimes be a bit of a lottery.
I'm an online shopper, so that's what I do in my free time. A lot of online shopping, and I just like to see new styles and new people.
Women's sports is still in its infancy. The beginning of women's sports in the United States started in 1972, with the passage of Title 9 for girls to finally get athletic scholarships.
In the seventies we had to make it acceptable for people to accept girls and women as athletes. We had to make it okay for them to be active. Those were much scarier times for females in sports.
I like a lot of sports. Especially football - it's my favourite sport. My uncle played football in Barcelona for nine years and played for Spain in three World Cups.
The thing, when you're down two sets to love, is to stay calm, even though it's hard, because people are freaking out, people are worried for you.
I don't wear makeup on the court, but I always wear sunblock. I love getting done up and wearing makeup away from the court though!
Every year I go to Broadway to see a musical - I like the music. I saw 'Mamma Mia;' I saw 'Les Miserables;' I saw 'Phantom of the Opera' like six, seven times.
I won two ITF tournaments in Japan in two weeks. I had to qualify for both of them, which meant that I won 16 matches in 15 days.
I think I have handled things pretty well last year and this. What I have to do now is try do it even better.
Everybody always talks about the pressure of playing at Wimbledon, how tough it is, but the people watching make it so much easier to play.
When I'm training in December, I have to eat like 6,000 calories a day to maintain my weight. It's a bit tiring.
I think if I believe in something strongly enough, I'm pretty outspoken about it.
I got to play in a crowd, play in Wimbledon finals, be the guy on a Davis Cup team for a while. Those are opportunities not a lot of people get.
The selfish thing about an athlete is you always look at the side of things where you say I could've done that better.
