“Man must not only make himself: the weightiest thing he has to do is to determine what he is going to be. He is causa sui to the second power.”

Source: Motivation and Personality (1954), p. 93.
Context: A musician must make music, an artist must paint, a poet must write, if he is to be ultimately at peace with himself. What a man can be, he must be. This need we may call self-actualization. This term, first coined by Kurt Goldstein, is being used in this paper in a much more specific and limited fashion. It refers to the desire for self-fulfillment, namely, to the tendency for him to become actualized in what he is potentially. This tendency might be phrased as the desire to become more and more what one is, to become everything that one is capable of becoming.
Variant: What I am saying is that it is not so much what man is that counts as it is what he ventures to make of himself. To make the leap he must do more than disclose himself; he must risk a certain amount of confusion. Then, as soon as he does catch a glimpse of a different kind of life, he needs to find some way of overcoming the paralyzing moment of threat, for this is the instant when he wonders who he really is - whether he is what he just was or is what he is about to be. Adam must have experienced such a moment.

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.
