Never stop when you are stuck. You may not be able to solve the problem, but turn aside and write something else. Do not stop altogether.

I would try to keep myself going by inventing games, and I would sing songs, a song beginning with “A,” “Always.” “Because,” “Charmaine,” “Daisy,” go through the alphabet. ... I would try to remember the states in the United States of America.

I was really vulnerable right before I left the coach, and I said to him, 'Are you still going to love me if I don't win this thing?'

The real problem is that the pain actually gets worse. You have created massive acidosis in your muscles so there is a huge quantity of hydrogen ions and the pH in your blood changes. For 15 minutes you lie there thinking, "God, this is really bad. I'm going to die. It has never been this bad before." And every time you think exactly the same thing. You have to lie to yourself by saying you're not doing a second set. Then, without moving for 15 minutes, almost to the second, I would roll over and think, "OK, I think I can do a second set now." During those sessions I have never felt more alive or so close to death.

The word says it all. To be a friend means that they are always there, for the good or the bad.

If I don't do that with the bottles, then I sit down, I could be thinking of something else. If I do always the same things, it means that I am focused and I'm alert to think purely about tennis.

Selfishness and no respect for the others.

Playing tennis, competing, winning, but also being at home in Spain, in Majorca, with my friends and family.

Just normal people from my hometown, from my country.

I don’t think I have one in particular. I am pretty calm. Just some small things that I better not comment on :-).
