Yup -- deliberate thought -- the most astonishing power we have! Maybe it looks like some people fall back into their old-pain patterns because they are unlucky or they're plagued by bad energy, but I think the real reason is: you've got a choice to deliberately think your thoughts, otherwise your thoughts think you. Either you take 100% responsibility for your life, or you don't.
There's nothing mystical about success in personal development. Just choices!
