I recently finished reading "The Artist's Way" recommended to me by my Uncle Jim. It's a workbook to help you unblock your creativity.
Hands down, it is one of the 5 best books I've ever read and the most helpful to me. (Some of the others are the Alchemist, and of course the Scriptures)
If you are a blocked creative, or want to be artistic, but don't think you have the time, don't think you're good enough, or whatever, this book will help you.
It focuses on "Daily Pages" where you just write 3 pages everyday, whatever you want, and "Artist Dates" where you take yourself on a creative date, usually window shopping, nature walks, or just treating yourself to something you've always wanted to do.
It has helped me unlock more creativity and in my opinion, become a better person.
I loved it!
