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

Never complain and never explain.

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

Be gentle to all and stern with yourself.

To know oneself, one should assert oneself.

It's always too early to quit.

Expect problems and eat them for breakfast.

Quality is not an act, it is a habit.

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