Failure & age (Caldwell & Thomason)

The two hardest things to contemplate in life are failure and age; and those are one and the same. Perfection is the natural consequence of eternity: wait long enough, and anything will realize its potential. Coal becomes diamonds, sand becomes pearls, apes become men. It's simply not given to us, in one lifetime, to see those consummations, and so every failure becomes a reminder of death.
