My curiosity drives me in different directions, but until I have invested lots of my time—months, years—I have no idea whether a chosen subject will sustain my interest. Sometimes I toss into the trash various drafts of what I have written, while at other times I put them aside, file them away, reread them a year or two later, rewrite and refile them perhaps, or decide that they are not worth saving after all, and so I tear them up and “rid myself of them forever."
