One isn't necessarily born with courage, but one is born with potential. Without courage, we cannot practice any other virtue with consistency. We can't be kind, true, merciful, generous, or honest.
Shallow men believe in luck, believe in circumstances: it was somebody's name, or he happened to be there at right time, or it was so then, and another day it would have been otherwise. Strong men believe in cause and effect.
Both classically- and romantically-minded spirits-inasmuch as these two species always exist-occupy themselves with a vision of the future: but the former do so out of a strength of their age, the latter out of its weakness.
So sometimes things are ahead and sometimes they are behind; Sometimes breathing is hard, sometimes it comes easily; Sometimes there is strength and sometimes weakness; Sometimes one is up and sometimes down. Therefore the sage avoids extremes, excesses, and complacency.
A wise man ought always to follow the paths beaten by great men, and to imitate those who have been supreme, so that if his ability does not equal theirs, at least it will savor of it. Let him act like the clever archers who, designing to hit the mark which yet appears too far distant, and knowing the limits to which the strength of their bow attains, take aim much higher than the mark, not to reach by their strength or arrow to so great a height, but to be able with the aid of so high an aim to hit the mark they wish to reach.
My opportunities were still there, nay, they multiplied tenfold; but the strength and youth to cope with them began to fail, and to need eking out with the shifty cunning of experience.
