Who am I? How would I answer that question?

I would say that I am a tennis player because i love tennis these days. this summer, i played tennis 4 times a week and practiced for 8-10 hours a day. and i spent most of time thinking about how i can win a singles game. i could say i am  made of tennis!
there was an official tennis match on september 10. a group match. each team has 5 singles and 4 doubles and the group which got first 5 games wins. Unfortunately we lost by 3-6against Keio tennis cirsle called "Keio Windsor". my tennis circle has never suceeded in passing the first round since this circle was established. I definitely want to pass the first round inext year.
