You never know what motivates you.
Always desire to learn something useful.
Never complain and never explain.
It's always too early to quit.
The dog that trots about finds a bone.
Only the educated are free.
To know oneself, one should assert oneself.
The secret of getting ahead is getting started.
Either you run the day or the day runs you.
Be thine own palace, or the world's thy jail.
There's an unseen force which lets birds know when you've just washed your car.
