Creativity is one of my all time favorite subjects. The books listed below are some of my favorites on this subject.
The New Creative Artist: A Guide to Developing Your Creative Spirit is my latest find in books on creativity and I love it! I've spend hours upon hours reading and doing the daily exercises in this book. Convinced that creativity can be learned, the author starts you off on a creative joy ride through the mechanics of creativity and into imaginative mind games.
Art Escapes is very much like The New Creative Artist in that it contains daily exercises and inspirations for discovering greater creativity and artistic confidence.
