In a recent interview with author and illustrator Brian Lies at Greetings From Nowhere (part of Robert's Snow- Blogging for the Cure) one of the tips Brian shared was to draw as much as you can. He said:
My ability to draw waxes and wanes. When I'm in the writing stage of a book and don't draw for several weeks, my drawing becomes terrible. It's only after drawing daily for a week or so that my skills return, and the mental muscles get back into shape. But it's important to build those mental muscles first--and the only way to do it is by spending time practicing.
I totally relate to this! I actually think most of life is about practice-- whatever skill you are trying to master. And it reminds me to keep a sketchbook with me wherever I go. Even for the smallest of scribbles.
