To know oneself, one should assert oneself.
Things do not happen. Things are made to happen.
Only the educated are free.
The wise does at once what the fool does at last.
To be a good loser is to learn how to win.
Expect problems and eat them for breakfast.
Be gentle to all and stern with yourself.
The secret of getting ahead is getting started.
By failing to prepare, you are preparing to fail.
Know or listen to those who know.
It's the same old story you've heard a thousand times. Somebody's trust gets broken. Somebody's left behind.
