I'm reminded of a line (I think it's from Dorothy Parker) in reaction to something someone said about their prose just flowing easily out, like a player piano scroll. The response was something along the lines of, "Yes, and just as original..."

Painting is hard, writing is hard, raising children is hard, sculpting is hard, LIFE is hard.

Also, I think the Garrison is reacting to the "oh woe, is me. I have such a sensitive, artistic nature" school of "writing".

Oh hell, I gotta break out my copy of Art And Fear.

And if you need to bitch about writing, please do.
