Motivation is the key to success. You should be motivated by the challenge.Its the same in tennis as in life. Never stay still but constantly do something new, to do something that interests you. You need new challenges all the time to fuel your passion. Want to live every moment of your life to the full. Feel the buzz of going on court and accepting the challenge. Be like a gambler in a casino who can feel the rush of adrenalin not just when he's on a roll, but all the time. He gambles because he needs that buzz, he wants to experience it every moment of his life. Thats the way to play and thats the way you should want to lead your life, your tennis. Enjoy the excitement of a challenge to make you feel alive.
