There is a powerful Law of Attraction technique that I use in my daily life, called Dream Building. It states that the best way to make your dreams a reality is to actually experience them. Dream building is my favorite thing to do when I travel. It motivates and inspires me to raise my game and achieve my dreams by redirecting my focus towards what it is that I want most in life.
The problem comes about whenever we attempt to control our reality without first adjusting our vibration. No amount of physical manipulation will create the world that we wish to see. All of the work is done on the inside, in our minds. This means that no amount of action alone will produce the results that we desire. However, once we gain the ability to condition our minds to our desired frequencies of vibration, our physical reality quickly follows suit and reflects back to us our new vibration.
Feel it. Feel the way you will now after receiving your wish. You must act, speak, and think as if you are receiving it now. This is actually the most important, powerful step in using the Law of Attraction because this is where it starts working, and sometimes if you do this you don't feel like you need it anymore because you feel like you already have it! Therefore, the universe will manifest this thought and feeling, and you will receive it.
Be like a kid who allows no impossibility to enter her manifesting realm. "Feeling" helps us release any doubt and negative energy. It generates excitement and positive feelings, which support us to take inspired action! So go test drive that car you want, or feel what it will be like to have the perfect partner in your life, because feeling is believing!
Your second point is an interesting discussion. You are correct that in its infancy, psychology was criticized for claiming to be a scientific field and not living up to that assertion by performing quality research. I believe that this question has been put to rest as the rigors of publishing in psychology require randomized, double-blind, placebo controlled trials.
The so-called secret put forth in the best selling book The Secret represents ancient wisdom found within Kabbalah, or Jewish mysticism. The Kabbalists didn’t call this the Law of Attraction, but they knew and used the same principle—focusing thought and feeling on what you desire—for manifestation. Here are two reasons why manifestation doesn’t always occur.
