Man's ideal state is realized when he has fulfilled the purpose for which he is born. And what is it that reason demands of him? Something very easy-that he live in accordance with his own nature.
Seneca the YoungerThere is nothing that we can properly call our own but our time, and yet everybody fools us out of it who has a mind to do it. If a man borrows a paltry sum of money, there must needs be bonds and securities, and every common civility is presently charged upon account. But he who has my time thinks he owes me nothing for it, though it be a debt that gratitude itself can never repay.
