Emily Fletcher shared in Stress Less, Accomplish More; visualization is the part of the method that I feel the most lost with, so I thought a book on it would be worth reading. I did start it back in like April, but I kind of lost interest; I restarted reading it about a week ago, and finished it yesterday.
Creative Visualization gives you the basics of how to use creative visualization within your life (basically, by changing the way you talk to yourself and believing that the universe is plentiful for everyone, you can start to manifest your desires in your own life). Gawain then gives you a whole bunch of tools to help you bring creative visualization into your life (through using writing, creating vision boards/treasure maps, using mantras to help you change your negative self talk, etc).
I found the book a bit tough to get through though. It's not the type of book that you can easily read from cover to cover in one sitting. For me, it was like I could only read so much of it before having to go off and do something else (almost like I needed time to really consider what was being said). I did like that she gives you so many different tools to try; you can easily choose one or two that sound interesting to you, and ignore anything you don't like the sounds of.
