After the first shock of recognition - a sudden sense of "this is what I'm going to write" - the novel starts to breed by itself; the process goes on solely in the mind, not on paper. I feel a kind of gentle development, an uncurling inside, and I know that the details are there already, that in fact I would see them plainly if I looked closer, but I prefer to wait until what is loosely called inspiration has completed the task for me.
Vladimir NabokovTo a greater or lesser extent there goes on in every person a struggle between two forces: the longing for privacy and the urge to go places: the introversion, interest directed within oneself toward one's own inner life of vigorous thought and fancy; and extroversion, interest directed outward, toward the external world of people and tangible values.
