I am new to all this so I found this and yes the presentation is long but interesting for someone that knows next to nothing about this subject. I went ahead and ordered the digital and hard copy. From what I have read so far and what I have received is great and informative and very well researched. For all of the one star complainers this isn't a magic fix, you have to change your life for it to work, you are paying for the research they have done and the time spent. Of course you can do all that yourself but you will get lost in the tons of information. For those of us new to this this is a great source of resources and I have found it invaluable.
