Things do not happen. Things are made to happen.
If you think you can do it, you can.
Either you run the day or the day runs you.
Be gentle to all and stern with yourself.
Always desire to learn something useful.
Do not weep do not wax indignant. Understand.
Without hard work, nothing grows but weeds.
Expect problems and eat them for breakfast.
Know or listen to those who know.
To be a good loser is to learn how to win.
