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 must take care to live not merely a long life, but a full one; for living a long life requires only good fortune, but living a full life requires character. Long is the life that is fully lived; it is fulfilled only when the mind supplies its own good qualities and empowers itself from within.
Seneca the YoungerThe things which we hold in our hands, which we see with our eyes, and which our avarice hugs, are transitory, they may be taken from us by ill luck or by violence; but a kindness lasts even after the loss of that by means of which it was bestowed; for it is a good deed, which no violence can undo.
