Try it yourself. Throw your left hand into the air and say "I want" and state one of your goals. Immediately throw out your right hand and say "but..." and state a condition ("but I don't have it...but I don't know how...."). Notice the strong shift in your body? Now once again throw your left hand out and firmly state an intention. Do it again. And again. That's the key to manifestation - a firm stance, no wobbling!
