"The part of life we really live is small."
"For all the rest of existence is not life, but merely time. Vices beset us and surround us on every side, and they do not permit us to rise anew and lift up our eyes for the discernment of truth, but they keep us down when once they have overwhelmed us and we are chained to lust. Their victims are never allowed to return to their true selves; if ever they chance to find some release, like the waters of the deep sea which continue to heave even after the storm is past, they are tossed about, and no rest from their lusts abides ...
... Men do not suffer anyone to seize their estates, and they rush to stones and arms if there is even the slightest dispute about the limit of their lands, yet they allow others to trespass upon their life—nay, they themselves even lead in those who will eventually possess it. No one is to be found who is willing to distribute his money, yet among how many does each one of us distribute his life! In guarding their fortune men are often closefisted, yet, when it comes to the matter of wasting time, in the case of the one thing in which it is right to be miserly, they show themselves most prodigal."
- Seneca : On the Shortness of Life.
