You never know what motivates you.
Be thine own palace, or the world's thy jail.
Be kind whenever possible. It is always possible.
Be gentle to all and stern with yourself.
If you can dream it, you can do it.
Never complain and never explain.
Problems are not stop signs, they are guidelines.
The dog that trots about finds a bone.
Always desire to learn something useful.
Things do not happen. Things are made to happen.
Language, philosophy, and science are interwoven into the design of words, which are manipulated to create surprising illusions.
