I've probably blogged this thought seven or eight times before, but I'll say it again. Revision gives me little joy. I love composing and first draft writing, which almost always feel creative, new, fun, and energizing.
Revision, not so much. I love being done with revisions. But going back to a piece of writing and actually engaging in the work of revision seems, well, slower. Even when making big-time changes, I don't usually capture that feeling of newness.
