If we do wrong and no harm comes of it, we are not thereby justified. If we did evil and good came of it, the evil would be just as evil. It is not the result of the action, but the action itself which God weighs.
I shift between mediums very frequently. Instead of taking a break from writing, I just write in a different medium or in a different way or for a different purpose, so that I don't actually stop writing - I just go to something else. Like going from a big symphony to a piano piece is great and very refreshing, I find. And then going from that to a big concerto, and then having to go out and play.
