I try to be myself and, of course, be a good role model. I don't really find it hard, but you think about what you do and that other people look up to you.
It's better to have done because then you know what the player is going through and you understand the pressure, but then on the other hand I know a lot of people that were good players but not good coaches, and vice versa.
There are some guys you have problems beating because of their style - I always had difficulties with guys like Michael Chang and Andre Agassi because their returns were so good and they played so well in defence.
My legacy doesn't matter. It isn't important that I be remembered. It's important that when I stand before the Lord, he says, 'Well done, good and faithful servant.' I want to finish strong.
Find a good teacher, as I found for my sons. I feel the worst thing you can do is to try and teach your own children yourself, because there is a natural rebellion that occurs.
I haven't been in tennis for that long, but what I can say is that we have a lot of young guys at the top who are willing to do a lot of good things for tennis in general.
All the reading in the world cannot immunize you from the devastating effects of psychopaths. Everyone, including the experts, can be taken in, conned, and left bewildered by them. A good psychopath can play a concerto on anyone's heart strings.
I still take advice from my mum on what clothes look good on me. I used to listen to her a lot more, but I've started to choose my own things from time to time.
Everything I did in high school was focused on microbiology, looking at things like algae under a microscope for hours on end. When I was 13, I saved up $100 to buy a good used microscope. I was obsessed with microorganisms.
If you go to a big city anywhere in the world and you need a doctor, just ask me. I can tell you who's good and who's bad. I've even considered writing a guidebook.
I've thrown away lots of my old diaries - you never know who might get their hands on them. But I have kept a few notes on the good old days.
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.
The thing is, it's not good anyway for eight-year-olds to be out there playing tennis tournaments so soon in their lives. But when I did get to play in a tournament, when I was nine, I was overjoyed.
I am a particular fan of integrative exercise - that is, exercise that occurs in the course of doing some productive activity such as gardening, bicycling to work, doing home improvement projects and so on.
I think there's a supreme power behind the whole thing, an intelligence. Look at all of the instincts of nature, both animals and plants, the very ingenious ways they survive. If you cut yourself, you don't have to think about it.
Nature is at work. Character and destiny are her handiwork. She gives us love and hate, jealousy and reverence. All that is ours is the power to choose which impulse we shall follow.
For over two billion years, through the apparent fancy of her endless differentiations and metamorphosis the Cell, as regards its basic physiological mechanisms, has remained one and the same. It is life itself, and our true and distant ancestor.
My father was a progressive farmer, and was always ready to lay aside an old plough if he could replace it with one better constructed for its work. All through life, I have ever been ready to buy a better plough.
Love... Force it and it disappears. You cannot will love, nor even control it. You can only guide its expression. It comes or it goes according to those qualities in life that invite it or deny its presence.
You see, every creature alive on the earth today represents an unbroken line of life that stretches back to the first primitive organism to appear on this planet; and that is about three billion years.
We have fallen in love with the body. That's that thing that looks back at us from the mirror. That's the repository of that lovely identity that you keep chasing all your life.
