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. – Aristotle

Nothing great is created suddenly, any more than a bunch of grapes or a fig. If you tell me that you desire a fig. I answer you that there must be time. Let it first blossom, then bear fruit, then ripen. – Epictetus
