I just finished a story, and now I have to put the file away and leave it alone, not look even at one paragraph, because I will find a typo, which I will fix, and then there'll be a sentence that needs tightening, a line of dialogue that'll sound more real if I futz with the syntax, a line to cut and paste somewhere else, and all of a sudden I'll have a chain of revisions and it'll be two hours from now, and why can't I just enjoy that I've finished something and that this, for the next little while, is the most I can do?
