The purpose of life is not to be happy. It is to be useful, to be honorable, to be compassionate, to have it make some difference that you have lived and lived well.

Do not be too timid and squeamish about your actions. All life is an experiment.

Do not go where the path may lead, go instead where there is no path and leave a trail.

Don't waste yourself in rejection, nor bark against the bad, but chant the beauty of the good.

Nothing great was ever achieved without enthusiasm.

Nothing is at last sacred but the integrity of your own mind.

Ralph Waldo Emerson
