I tend to be reading at least three or four books at the same time, except when I start a book that is so captivating that I read it in one sitting. For some books, reading bits and pieces here and there actually makes for better, gradual absorption. Creativity For Life by Eric Maisel is one of these books, giving me a nice kick in the b*tt each time I pick it up.
There is a prevailing myth that creativity is something that just comes to us, like lightning from the sky, or that it is all fun and play, but the reality as most artists know is that it is more often than not hard work (albeit it fun in a masochist kind of way).
While many parts of the book deal with some of the more destructive personality traits of many artists, even for those of us who do not suffer from depression, alcohol abuse etc. the book is a great resource for introspection. If you just need to overcome a creative block, get motivated or disciplined about creative pursuits, or really want to understand aspects of your artist personality this book is one of the most comprehensive I have seen. For me the most useful was the extensive chapter on the many, many causes of blocks (20 are discussed in great detail!).
