It's always too early to quit.
The secret of getting ahead is getting started.
After a storm comes a calm.
Never complain and never explain.
Leap, and the net will appear.
Who seeks shall find.
Quality is not an act, it is a habit.
The dog that trots about finds a bone.
Be thine own palace, or the world's thy jail.
You never know what motivates you.
The whole business of marshaling one's energies becomes more and more important as one grows older.
