It's always too early to quit.
Never complain and never explain.
Without hard work, nothing grows but weeds.
After a storm comes a calm.
Be thine own palace, or the world's thy jail.
The dog that trots about finds a bone.
Be kind whenever possible. It is always possible.
Always desire to learn something useful.
The secret of getting ahead is getting started.
You never know what motivates you.
I can always see what I've done wrong. I'm always learning. I'm the perennial student.
