To know oneself, one should assert oneself.

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

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

Never complain and never explain.

Be gentle to all and stern with yourself.

Quality is not an act, it is a habit.

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

It's always too early to quit.

Either you run the day or the day runs you.
