Never complain and never explain.

Go for it now. The future is promised to no one.

Quality is not an act, it is a habit.

Always desire to learn something useful.

Expect problems and eat them for breakfast.

Be thine own palace, or the world's thy jail.

The most effective way to do it, is to do it.

Be gentle to all and stern with yourself.

The wise does at once what the fool does at last.
