Never complain and never explain.
Be kind whenever possible. It is always possible.
If you think you can do it, you can.
Begin to be now what you will be hereafter.
Always desire to learn something useful.
You never know what motivates you.
The dog that trots about finds a bone.
By failing to prepare, you are preparing to fail.
To be a good loser is to learn how to win.
Without hard work, nothing grows but weeds.
I think it's more important to be fit so that you can be healthy and enjoy activities than it is to have a good body.
