A strong midsection is very important in tennis and it helps to avoid back injuries. I sometimes do have bad days on the court, but they are actually rare as long as I have enough down time. It's important to do yourself a favor and just take it easy once in a while. Also, I remember that my job is a great one, it's never dull, and I look forward to it. For me, that means giving 200 percent and being very intense.
Success is simple.
When the day is over I have to feel that I gave my all and tried all options to be my best for that day. After that, winning or losing is irrelevant. It always feels better to win, but to lose not trying is inexcusable. There is no failure as long as you give your all because there is always going to be another chance as long as you learn from each match. My second love in sports is beach volleyball.
