Among the many books I could recommend are two that I think should be on every artist's shelf — not just to have read, but at the ready to reference over and over again. These are strictly about creativity and not technique.
The first is Austin Kleon's Steal Like an Artist. OK, not a reach here... it's a best seller. But I have to say that if you've never come across these concepts before, they are valuable tools for deconstructing creative misconceptions, roadblocks and what it really can mean to act as an artist. Austin Kleon has made it his business (literally) to provide inspiring ideas that can help any artist keep the floodgates of creativity open and unfettered. If it's not required reading in the first year of art school by now, it should be.
The second book may not be so widely known. I discovered Art & Fear on the shelf at a local bookstore and had never heard it recommended nor even mentioned by anyone else, ever. I have purchased it many times since... because every time I've lent it out, it didn't get returned. I put this down to the the idea that I was right and that the artist I'd lent it to really did need it. Now I keep a copy for myself, and if I think someone needs it, I buy another copy and simply give it to them.
David Bayles and Ted Orland systematically break down every argument you could have against doing your artwork. The concept is simple — just do it. However, this writing explains away the most common fears and anxieties that every artist has felt rising up and whispering to them "Stop". Many times when I have come up against a fallen tree in the creative road, it has been this book that has helped me move on. The authors take an intimate journey through what it means to be at all apprehensive about your creativity and what it means not to. I cannot recommend this book enough.
Time for a shameless plug.
If you like the artwork on this site, a welcome addition your own studio bookshelf might be the companion book to my series The Thirty Million Dollar Suit That Never Gets Pressed. There is the 20 page Gallery Edition and the 96 page Deluxe Studio Edition only available through my store Ink On Paper as limited editions. When those are gone, there will still be an open edition available through Blurb.
