Expect problems and eat them for breakfast.
Begin to be now what you will be hereafter.
It's always too early to quit.
You never know what motivates you.
If you've got a talent, protect it.
Be gentle to all and stern with yourself.
Problems are not stop signs, they are guidelines.
The wise does at once what the fool does at last.
Wherever you are - be all there.
Go for it now. The future is promised to no one.
Seems like most of the kids today are into other sports other than tennis.
