“What happens is a continual surrender of himself as he is at the moment to something which is more valuable. The progress of an artist is a continual self-sacrifice, a continual extinction of personality.”

The Dominant Idea (1910)
Context: It is not to be supposed that any one will attain to the full realization of what he purposes, even when those purposes do not involve united action with others; he will fall short; he will in some measure be overcome by contending or inert opposition. But something he will attain, if he continues to aim high.
What, then, would I have? you ask. I would have men invest themselves with the dignity of an aim higher than the chase for wealth; choose a thing to do in life outside of the making of things, and keep it in mind, — not for a day, nor a year, but for a life-time. And then keep faith with themselves! Not be a light-o'-love, to-day professing this and to-morrow that, and easily reading oneself out of both whenever it becomes convenient; not advocating a thing to-day and to-morrow kissing its enemies' sleeve, with that weak, coward cry in the mouth, "Circumstances make me." Take a good look into yourself, and if you love Things and the power and the plenitude of Things better than you love your own dignity, human dignity, Oh, say so, say so! Say it to yourself, and abide by it. But do not blow hot and cold in one breath. Do not try to be a social reformer and a respected possessor of Things at the same time. Do not preach the straight and narrow way while going joyously upon the wide one. Preach the wide one, or do not preach at all; but do not fool yourself by saying you would like to help usher in a free society, but you cannot sacrifice an armchair for it.

Collected Aphorisms
Context: Most of the time man does not do what he wills, but what he has willed. Through his decisions, he always gives himself only a certain direction, in which he then moves until the next moment of reflection. We do not will continuously, we only will intermittently, piece by piece. We thus save ourselves from willing: principle of the economy of the will. But the higher man always experiences this as thoroughly immoral.
