You have to think for an email. What's the subject? What's it about? It takes two seconds to think about that. So you have to think, Is this a work thing or a social thing? Which? Then you get into a situation that you don't want to be in, because then people are thinking about it too much.

I started as an artist and I had a side job moving some heavy boxes for a publishing company. They had just gotten a Mac for their art department, the department that creates the book covers. I was kind of showing the art director a thing or two about how to use a Mac. And one day everyone went out to lunch and I jumped on the computer and designed a book jacket and slipped it in the pile to go to the review board in New York. They picked my jacket and when the art director got back to Boston, he wanted to know who designed it and I said, "Me." He was like, "The box guy?"
