Since "The Secret" has become mainstream making it to Oprah and since Abraham's messages are mentioned so much in Law of Attraction teachings, am adding this quote from one of their workshops which came in email.
Take what resonates and leave the rest.
"The thought that you think, you think, which attracts to it; so you think it some more, which attracts to it; so you think it some more. In other words, when you have an expectation, you've got a dominant thought going on, and Law of Attraction is going to deliver that to you again, and again and again. And you say "The reason that I believe this, is because it is true." And we say, the reason that you believe it, is because you've practiced the thought. All that a belief is, is a thought that you keep practicing.
