The Importance of Drawing in UX

The more we do it, drawings like a muscle and the more we exercise it, the stronger we get. Why start laying down layers and Photoshop and spending hours trying to make it pixel perfect when you can just draw it? So that's great. And mentorship huge. I just got a mentor recently. He's very cool. Helping me out already. Cal, if you could recommend one book to your listeners, what would it be and why?
