If you think you can do it, you can.
To be a good loser is to learn how to win.
I can, therefore I am.
The dog that trots about finds a bone.
Who seeks shall find.
Without hard work, nothing grows but weeds.
It's always too early to quit.
Problems are not stop signs, they are guidelines.
Things do not happen. Things are made to happen.
Be gentle to all and stern with yourself.
As a system of philosophy it is not like the Tower of Babel, so daring its high aim as to seek a shelter against God's anger but it is like a pyramid poised on its apex.
