Be gentle to all and stern with yourself.
To be a good loser is to learn how to win.
Be thine own palace, or the world's thy jail.
Know or listen to those who know.
You never know what motivates you.
To know oneself, one should assert oneself.
Well done is better than well said.
Who seeks shall find.
If you think you can do it, you can.
By failing to prepare, you are preparing to fail.
Competition is the spice of sports but if you make spice the whole meal you'll be sick.
