I've said time and time again that if there's something I love more than making art (and food), it's books. In 2013, armed with colored pens (my medium of choice then) and my limited lettering and sketching skills, I decided to draw every book I'd read that year. I ended up doing only about seven book portraits, but I definitely read more than that! Here are three of them.
So Good They Can't Ignore You by Cal Newport. One of the best books I've read about balancing passion and skill-building in life.
Breakthrough! by Alex Cornell. This is the first book I read on the topic, and it has a combination of sensible and wacky suggestions from creatives around the world.
The Little Book of Talent by Daniel Coyle. Spoiler alert: talent = hard work = hours of deliberate practice. I am actually re-reading this book because I want to learn new skills this year.
