Marcus Aurelius
Meditations 4.47
If any god told thee that thou shalt die to-morrow, or certainly on the day after to-morrow, thou wouldst not care much whether it was on the third day or on the morrow, unless thou wast in the highest degree mean-spirited; for how small is the difference! So think it no great thing to die after as many years as thou canst name rather than to-morrow.
Marcus Aurelius, Meditations 4.47, translated by George Long
Just as, if a God had told thee, Thou shalt die to-morrow or in any case the day after, thou wouldest no longer count it of any consequence whether it were the day after to-morrow or to-morrow, unless thou art in the last degree mean-spirited, for how little is the difference!—so also deem it but a trifling thing that thou shouldest die after ever so many years rather than to-morrow.
Marcus Aurelius, Meditations 4.47, translated by C. R. Haines
