A quick plug for Steal Like an Artist: 10 Things Nobody Told You About Being Creative by Austin Kleon.
I bought this book on someone's recommendation, without giving it much thought. It was so small and cartoonish when it arrived, however, that I assumed I had made a mistake. As it turned out, I enjoyed it. I found it simple but not simplistic. If your goal is to create, the brief lessons in the book could help you to jump-start your creative juices and get moving on actually making something. Or you could find a longer book that you will never finish and be happy to have an excuse not to make a start.
