Never complain and never explain.
What you do today can improve all your tomorrows.
Be gentle to all and stern with yourself.
Be thine own palace, or the world's thy jail.
If you're going through hell, keep going.
The secret of getting ahead is getting started.
Who seeks shall find.
You never know what motivates you.
Always desire to learn something useful.
Be kind whenever possible. It is always possible.
History is a tool used by politicians to justify their intentions.
