Although I don't work in a creative field, I definitely have my work face and my private face. In my experience most people do - by and large, work requires different things of people than home life.

Why in the world shouldn't creative people have the same division? If I had ever had even the tiniest bit of doubt that creating art wasn't work, reading your blog cured me of it!

(Side thought: why else would they be called "works of art"?)
