It's always too early to quit.

To know oneself, one should assert oneself.

Never complain and never explain.

Quality is not an act, it is a habit.

Be kind whenever possible. It is always possible.

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

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

Things do not happen. Things are made to happen.

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