Always desire to learn something useful.
To be a good loser is to learn how to win.
Never complain and never explain.
By failing to prepare, you are preparing to fail.
Be gentle to all and stern with yourself.
If you're going through hell, keep going.
Be thine own palace, or the world's thy jail.
Know or listen to those who know.
The wise does at once what the fool does at last.
You never know what motivates you.
The world is governed more by appearance than realities so that it is fully as necessary to seem to know something as to know it.
There is nothing so powerful as truth, and often nothing so strange.
Wisdom begins at the end.
