For me it does seem that this is all about faith. Not the religious or spiritual faith we have come to know, rather the faith in yourself and your ability to have what you want. You want something, you 'do things' to get yourself to believe it is possible, this opens up your eyes to opportunities, and
you take action. Not much different than what Tony Robins teaches is it? Tony Robbins and the folks with "The Secret" are good at marketing. It is nothing new, it is not a secret. By buying into their methods we are help them to manifest their intentions aren't we?
Many years ago I read the books "The Magic of Believing" by Claude M. Bristol, "Psycho-Cybernetics" by Maxwell Maltz , and "The Power of the Subconscious Mind" by Dr. Joseph Murphy. This books have slightly different approaches but in many ways talk about self improvement through the method of watching and controlling your thoughts, and visualization. Just like variations in religions, there are methods and systems in place to give you the answers to life.
I am always skeptical when I see people out to help people with the 'intention' of making money at it. (Sorry Steve, you do great work..not a slam on you at all

) There is an opportunity to take advantage of people. But I guess sometimes it takes a new way, a 'system' (I am really starting to not like that word) to get us to look at things in a new way. If "Awaken the Giant Within" or "The Secret" is what it take then that is what it takes.
But still, it all may just be an illusion.
