I have been editing all week, but not my own work. No, I cheerily volunteered over the course of the past several months to edit many different peoples' writings, and then they all needed doing this week. I hope - I really, really hope - that I have some skill in editing, at least editing for other people, given the number of people on which I am inflicting my feedback. I have never been much good, alas, at editing my own work: I already know what I've written so I have trouble seeing what I actually did write.
So far this week, I've marked up three abstracts and nine essays, with another six essays to go by tomorrow.
