Julia Cameron's book is truly amazing IF you put her recommendations into practice: doing the morning pages, weekly artist date and a few of the exercises each week. I am currently in week 6 (of 12) and after working my way through it, I have honestly noticed more synchronicity and a general feeling of more possibility in the world. There are more practical get-going-and-write books out there, such as Natalie Goldberg's Writing Down the Bones, but the Artist's Way is really fantastic at guiding you through the process of listening to your inner critic and doing the work despite your worries about quality, acceptance, etc.
