If you think you can do it, you can.
Be gentle to all and stern with yourself.
Who seeks shall find.
The most effective way to do it, is to do it.

Always desire to learn something useful.
If you can dream it, you can do it.
Never complain and never explain.
The dog that trots about finds a bone.
Be thine own palace, or the world's thy jail.
