Stamina

But I still believe that the unexamined life is not worth living: and I know that self-delusion, in the service of no matter what small or lofty cause, is a price no writer can afford. HIs subject is himself and the world and it requires every ounce of stamina he can summon to attempt to look on himself and the world as they are.

James Baldwin, from the introduction to Nobody Knows My Name
