The privilege of a serene and untroubled mind

The days of our present come one by one, and each day minute by minute; but all the days of the past will appear at your bidding and allow you to examine them and linger over them at your will. Busy men have no time for this. Excursions into all the parts of its past are the privilege of a serene and untroubled mind; but the minds of the preoccupied cannot turn or look back, as if constricted by a yoke. And so their life vanishes into an abyss.

~ Seneca
