Being an illustrator can be a kind of lonely business sometimes. Last winter, I bought a little TV and sometimes if I'm doing something really repetitive I'll turn on the TV for background noise.
One of the most difficult things I find working alone is trying to stay focused. I, like many illustrators, work from home. And as you can imagine there are lots of distractions around here like doing the house work or making dinner. Even though I have an awesome workspace, there are times when I will go to Starbucks or the local library to work. It helps me stay on task and also gives me a little human interaction.
