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 YoungerIt passes in the world for greatness of mind, to be perpetually giving and loading people with bounties; but it is one thing to know how to give and another thing not to know how to keep. Give me a heart that is easy and open, but I will have no holes in it; let it be bountiful with judgment, but I will have nothing run out of it I know not how.
Seneca the YoungerIt is essential to make oneself used to putting up with a little. Even the wealthy and the well provided are continually met and frustrated by difficult times and situations. It is in no man's power to have whatever he wants; but he has it in his power not to wish for what he hasn't got, and cheerfully make the most of the things that do come his way.
Seneca the YoungerNow we are not merely to stick knowledge on to the soul: we must incorporate it into her; the soul should not be sprinkled with knowledge but steeped in it.
