Drawing on the Right Side of the Brain Workbook: The Definitive, Updated 2nd Edition by Betty Edwards

A very fascinating and well-researched book that doesn't give you a 'step-by-step' guide to drawing, but instead teaches you to develop an artists' perspective. I think that understanding these concepts is  a much better starting point. I've been working through the exercises in this book slowly, while also drawing things that I like in between to keep myself interested.
