If you think you can do it, you can.
Never complain and never explain.
By failing to prepare, you are preparing to fail.
If you can dream it, you can do it.
The wise does at once what the fool does at last.
If you've got a talent, protect it.
Be gentle to all and stern with yourself.
Begin to be now what you will be hereafter.
The dog that trots about finds a bone.
The most effective way to do it, is to do it.
Seems like most of the kids today are into other sports other than tennis.
