Know or listen to those who know.
The wise does at once what the fool does at last.
What you do today can improve all your tomorrows.
Be gentle to all and stern with yourself.
To be a good loser is to learn how to win.
Begin to be now what you will be hereafter.
Leap, and the net will appear.
Things do not happen. Things are made to happen.
Go for it now. The future is promised to no one.
I can, therefore I am.
The ballplayer who loses his head, who can't keep his cool, is worse than no ballplayer at all.
