...with a click, my novel would be born; it would come out into the light suddenly transformed from the hypothetical text composed in my imagination into finished, tangible thing with a real and independent existence. The moment of clicking on the print button always gave rise to strange and powerful ambivalence--a combination of self-satisfaction, gloom and anxiety. Self-satisfaction for having finished writing the book. Gloom because taking my leave of the characters has the same effect on me as when a group of friends have to depart. And anxiety, perhaps because I am on the verge of delivering up into other people's hands something that I treasure.
