I've mentioned Austin Kleon here before, but here is an official recommendation. Read both of these books, now.
They're quick reads, about 45 minutes each from what I remember, and are immeasurably insightful if you're anybody, but especially if you're creative (ugh). They're also packed with great illustrations and sketches which make reading them a delight. They've helped me kickstart some creative endeavors, and furthermore, helped me get over the fear of sharing what I know and like.
I have them both if you need to borrow them, or you can buy them pretty much anywhere, but links to Amazon are below.
