Don't be too timid and squeamish about your actions. All life is an experiment.

This is the strangest life I've ever known.

The wise man does not expose himself needlessly to danger, since there are few things for which he cares sufficiently but he is willing, in great crises, to give even his life - knowing that under certain conditions it is not worthwhile to live.

I swear, by my life and my love of it, that I will never live for the sake of another man, nor ask another man to live for mine.

Your life is the fruit of your own doing. You have no one to blame but yourself.
