Let us therefore set out whole-heartedly,
leaving aside our many distractions and exert ourselves in this single purpose,
before we realize too late the swift and unstoppable flight of time and are left behind.
As each day arises, welcome it as the very best day of all,
and make it your own possession.
We must seize what flees.
—Seneca, Moral Letters, 108.27b-28a(resource) Ryan Holiday, The Daily Stoic
