We all sorely complain of the shortness of time, and yet have much more than we know what to do with. Our lives are either spent in doing nothing at all, or in doing nothing to the purpose, or in doing nothing that we ought to do. We are always complaining that our days are few, and acting as though there would be no end of them.
Seneca the YoungerHe is ungrateful who denies that he has received a kindness which has been bestowed upon him; he is ungrateful who conceals it; he is ungrateful who makes no return for it; most ungrateful of all is he who forgets it.
Seneca the YoungerMany men would have arrived at wisdom had they not believed themselves to have arrived there already.
Seneca the YoungerA dwarf is small even if he stands on a mountain; a colossus keeps his height, even if he stands in a well.
