It's always too early to quit.
By failing to prepare, you are preparing to fail.
Never complain and never explain.
If you think you can do it, you can.
Know or listen to those who know.
Leap, and the net will appear.
Be gentle to all and stern with yourself.
The dog that trots about finds a bone.
The wise does at once what the fool does at last.
I can, therefore I am.
So long as we can lose any happiness, we possess some.
