I can, therefore I am.

Do not weep do not wax indignant. Understand.

Things do not happen. Things are made to happen.

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

Always desire to learn something useful.

If you think you can do it, you can.

Without hard work, nothing grows but weeds.

Be gentle to all and stern with yourself.

It's always too early to quit.
