When some state or other offered Alexander a part of its territory and half of all its property he told them that 'he hadn't come to Asia with the intention of accepting whatever they cared to give him, but of letting them keep whatever he chose to leave them.' Philosophy, likewise, tells all other occupations: 'It's not my intention to accept whatever time is leftover from you; you shall have, instead, what I reject.' Give your whole mind to her.
Seneca the YoungerWe deliberate about the parcels of life, but not about life itself, and so we arrive all unawares at its different epochs, and have the trouble of beginning all again. And so finally it is that we do not walk as men confidently towards death, but let death come suddenly upon us.
