It's always too early to quit.
Never complain and never explain.
Only the educated are free.
Be gentle to all and stern with yourself.
Do not weep do not wax indignant. Understand.
Things do not happen. Things are made to happen.
The dog that trots about finds a bone.
Always desire to learn something useful.
By failing to prepare, you are preparing to fail.
If you think you can do it, you can.
I'm not hip, I'm not cool, I'm not glib.
