You never know what motivates you.
The secret of getting ahead is getting started.
Who seeks shall find.
The dog that trots about finds a bone.
Only the educated are free.
Always desire to learn something useful.
After a storm comes a calm.
Be thine own palace, or the world's thy jail.
What you do today can improve all your tomorrows.
Problems are not stop signs, they are guidelines.
