Read this text about a professional tennis player:

I am a professional tennis player.

I taught myself how to play tennis because my parents didn’t think sport was a good profession. Every day, I have a similar routine. I wake up early and make myself breakfast. Then I meet my coach on the tennis court and we train with each other for about four hours. We stop at about 12.30 and make ourselves lunch. Then we train for another four hours in the afternoon. I love my profession but I often worry that I will hurt myself during training.
