[T]o be resolute, to one's own self, is not a matter of finding one's true self and insisting upon it, at least not in any conventional sense of those terms. After all, whoever one might take one's "true self" to be can be overtaken by the world. What is more, and perhaps worse, one can die to that self by slipping into a depression that wrenches it away from one. To have found oneself and won oneself is in some cases to stick with who one has been heretofore and do so in the face of daunting social pressure, while in some cases it is to adapt flexibly to a new world or new dispositions. To win oneself is, in and of itself, neither to stick with who one has been nor to "wear the world's clothes lightly." Rather, to find oneself and win oneself is to see what is factically possible and important and to carry through with it, whatever its relation to who one has been heretofore might be. We can put this point by saying that the self one must find and win is who one is at this moment, but we cannot let the language of "moments" (Augenblicke) mislead us. Just as who I have-been is not who I have been, in the sense of the phases of my life that have gone by, so the moment of vision of which Heidegger writes in section 65 [of Being and Time] is not the now of clock-time, a tipping point between what has gone by and what is to come. This moment of vision, which might better be called a "moment of resolution," encompasses who I find myself to be and am able to go forward as.
