The condition of all who are preoccupied is wretched, but most wretched is the condition of those who labor at preoccupations that are not even their own, who regulate their sleep by that of another, their walk by the pace of another, who are under orders in case of the freest things in the world-loving and hating. If these wish to know how short their life is, let them reflect how small a part of it is their own.
Seneca the YoungerMen trust rather to their eyes than to their ears; the effect of precepts is therefore slow and tedious, whilst that of examples is summary and effectual.
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 YoungerEveryone rushes his life on, and suffers from a yearning for the future and a boredom with the present. But that man who devotes every hour to his own needs, who plans every day as if it were his last, neither longs for nor fears tomorrow.
