As I give thought to the matter, I find four causes for the apparent misery of old age; first, it withdraws us from active accomplishments; second, it renders the body less powerful; third, it deprives us of almost all forms of enjoyment; fourth, it stands not far from death.

Some men make a womanish complaint that it is a great misfortune to die before our time. I would ask what time? Is it that of Nature?

Six mistakes mankind keeps making century after century: Believing that personal gain is made by crushing others; Worrying about things that cannot be changed or corrected; Insisting that a thing is impossible because we cannot accomplish it; Refusing to set aside trivial preferences; Neglecting development and refinement of the mind; Attempting to compel others to believe and live as we do.
