Be kind whenever possible. It is always possible.
It's always too early to quit.
Things do not happen. Things are made to happen.
By failing to prepare, you are preparing to fail.
The dog that trots about finds a bone.
Always desire to learn something useful.
Expect problems and eat them for breakfast.
Never complain and never explain.
If you've got a talent, protect it.
After a storm comes a calm.
It sounds cliche, but success is your friends, your family, what you do, and if you're happy when you wake up.
