Be gentle to all and stern with yourself.

To know oneself, one should assert oneself.

Things do not happen. Things are made to happen.

Do not weep do not wax indignant. Understand.

It's always too early to quit.

Quality is not an act, it is a habit.

To be a good loser is to learn how to win.

If you're going through hell, keep going.

Always desire to learn something useful.
