I would suppose that a good writer would be able to shut out the outside world and tap away on her keyboard much like an actor must concentrate on his performance. I never found it difficult to accomplish the latter, but the former seems to occasionally exceed my grasp.
I am constantly put in new stages of awe as I learn more about other authors' discipline and diligence concerning their craft. It makes me feel very small. I do not seem to have a key to the floodgates at my disposal. I can either write or I can't. If I do write during a 'can't' time I guarantee that I'll be deleting it later (and have a little voice telling me this fact the entire time I'm writing).
On the plus side, "The Watcher" continues apace. It's turning out to be an interesting exercise in word choice and plot/character balance.
Here's my wish for good moods for all of you!
