The best thing that ever happened to my writing was getting this iPad + stylus. Forcing myself out of my house, into a space where I can only use a red pen has helped hugely.
I think there is something satisfying about using a red pen (even a virtual one). That it's therefore SATISFYING rather than frustrating to remove/edit your own work makes me happier to do it.
(Yes, I'm writing a novel, despite having not released the first one I wrote yet. Writing: I just really have trouble NOT doing it.)
