Step 4 is important for two reasons. The first is that it aligns you with your desires. The entire concept behind the Law of Attraction is that like attracts like. When you take action as if you’ve already gotten what you desire, you are sending a huge, loud and clear message to the universe that you’re serious. Actions speak louder than words, right?

I worked with a professional footballer once. He was getting very nervous about shooting goals. He kept missing even though he was very talented. I insisted that he kept watching himself on TV scoring goals and burned that image into his consciousness. I didn’t want him thinking about anything else. Every time he had a negative thought he was to switch that picture, either on the TV or on the TV in his mind. And he was to surround the thought with positive emotions of love and respect for himself.

Think about two droplets of water that are slowly moving towards each other. What happens as they get closer? They eventually get close enough that they attract each other and become one droplet of water instead of two separate ones. This occurs because they are of like vibration. Now, think about the same phenomena with a droplet of water and a droplet of oil. No matter how close you put them together they will not become one with each other. This is because their vibrations are too different from one another.
I do not claim to have all of those things either. However, I do have most of the things that I described and I managed to attain them through my value-based goals, plans, process-visualizations, and inspired action. I didn't ask the universe for it, you might say that the universe knew, but I was driven to get these things. I didn't act or pretend like I already had them.
The original creators of the law of attraction going back to the 1880s including Prentice Mulford,James Allen, Thomas Troward, William Walker Atkinson, Bruce MacLelland, Wallace Wattles, Napoleon Hill, Earl Nightingale, and W. Clement Stone promoted the belief that this is a universal law in which you attract only what you are thinking about. Modern LOA proponents such as Rhonda Byrne, Jack Canfield, Bob Proctor, John Assaraf, Joe Vitale, The Hicks family, and many others have stated similar beliefs.
Develop a belief in what I call the “reverse paradigm shift”. In other words, go for it before you have all the answers. Those so called negative energies (known as cognitive dissonance) are actually the magical seeds of creation and unlimited possibilities. Your destiny and your abundance will always be preceded by confusion and uncertainty. Ask anyone who’s been on the journey.
11) Blame the Victim:  The only reason that anything bad could ever happen to you is because you were thinking bad thoughts. If someone rear-ends you in a car – 100% your fault. If you get breast cancer – 100% your fault (not genetics). If you get raped or abused – 100% your fault. Children getting killed by terrorists, sick babies in the intensive care unit, victims of floods, hurricanes, natural disasters, the Holocaust – yes, their fault. We all know deep inside that this is ridiculous to even suggest. However, it is a basic, fundamental premise of the LOA. You NEVER attract something you are not thinking about. When anything bad happens to anyone, they are to blame. Don’t feel sorry for anyone who has cancer or a disease or starving children in poverty, they brought it on themselves. What causes obesity? Slow metabolism? No, fat thoughts.  From LOA experts, “Disease cannot live in a body that’s in a healthy emotional state.” (Bob Proctor).  “You cannot catch anything unless you think you can, and thinking you can is inviting it to you with your thought.” (From The Secret). “Good thoughts and actions can never produce bad results; bad thoughts and actions can never produce good results. Suffering is always the effect of wrong thought in some direction.” (James Allen). “If man will think only thoughts of perfect health, he can cause within himself the functioning of perfect health…” (Wallace Wattles). “Every individual creates every aspect of their experiences – we are in complete control of our health throughout our entire lives. There are no accidents.” (Esther Hicks).
Everyone wants to be lucky. We all want things to go our way and for life to deliver great opportunities, an inflow of money and people whom we get along with. Some seem to have all that. It looks so easy for them while the rest of us struggle along, doing our best and hoping for a lucky break. Thankfully, there are ways you can give the universe a nudge to help you attract good luck.
Think about the strengths and energies that make you unique. When you were a child you thought to yourself “Wow, I am ME. Nobody else is me or can feel the feelings I feel. They’re mine alone. This energy is uniquely my energy.” Then, of course, the world trained you out of this way of seeing things. You wanted to be the same as everyone else (or at least, they wanted you to be the same). Breaking free and removing failure from your vocabulary allows you to follow your bliss with ease.
The author demonstrates how good luck is a matter of personality. Factors like a healthy self-image and certain other attributes can change a negative and failure-prone personality to a positive one that admits no defeat and recognizes that good luck is not an accident. In reality, "good luck" means the attraction of favorable chances by a positive mind-set within. Personality factors that attract luck include a high energy level, generosity and a firmly held belief that one is lucky. Also, the will to attract luck, in the author's own words: "The extent to which we make ourselves luckier is likely to be directly proportional to the force of our will to be lucky. The will to be lucky is the crux of our internal development, the channel through which we can realize our full potentialities as lucky human beings." This is a pleasant read with valuable practical advice that will benefit the reader if applied to her/his life.

Within days from now you can attract your true love…set up a business that will change the world…get a better job than what you ever imagined possible…start to reclaim your health…rediscover your confidence and connect with the bliss of your true purpose. I’ve seen it happen so many times to people I know and clients of mine. Accelerated learning is a choice that allows you to build all the beautiful, powerful beliefs which will get you there quickly.

One of the most important elements of using visualization tools is to find the methods that best maintain constant focus on your objectives. Some people find different forms of visualization more powerful than others, so we’ll help you find the visualization styles that infuse you with the most intense sense of confidence and optimism. In addition, you’ll learn how to combine your new visualization tools with more positive ways of interacting with others, helping you to live and behave like you have already accomplished your goals.

The author demystified luck as something random and breakdown several conditions in attracting luck with ample examples. His style of language can take some efforts to understand but it's worth a read as one may understand why he is not inclined not rub shoulders with luck in the past but this would change if the principles from the book is applied.
Throw emotion and energy into everything you do. Even negative emotions can be transmuted into positive. Did you ever see someone red in the face with anger suddenly see the humor in a situation and burst into laughter? It can be one of the most beautiful things to witness. Do everything you do with emotion and the universe will love you for it. The law of attraction brings a tidal wave of energy that flows through emotion.
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.
10) Blame Yourself: As the LOA is supposed to be a perfect, universal law, positivity should ALWAYS attract more positivity. The corollary of this is that you alone are completely responsible for any goal that was not successfully achieved, no matter how unrealistic the goal. This assumes that you not only control your thoughts and actions, but also those of everyone around you…and nature. The fact is, that you don’t. Sorry to break that to you.
I sit down to write when there is an inspiration within to do so and then the words just flow through. These writings are not meant to create belief systems, dogmas, agendas or techniques. All these are just structures used by the "Me" to enhance itself. The real purpose of these writings, if any, is to awaken the recognition of your true nature. You don't need external guidance because it's already within you. All that's needed is that you become receptive to it. These writings are just meant to point you back to this place of receptivity.

The Spiritual Explanation: Many people believe that the Law of Attraction works by aligning God or the Universe with our wishes. We are all made of energy, and our energy operates at different frequencies. We can change our frequency of energy with positive thoughts, especially gratitude for what we already have. By using grateful, positive thoughts and feelings and by focusing on our dreams — rather than our frustrations, we can change the frequency of our energy, and the law of attraction brings positive things into our lives. What we attract depends on where and how we focus our attention, but we must believe that it’s already ours, or soon will be.
From this knowledge, it can be stated that your entire “reality” is all within your head. There is nothing “out there” even though it seems like it. It’s the case of the popular question, “if a tree falls in a forest and nobody’s there to hear it, does it make a sound?” The idea is that you cannot experience your reality without actively perceiving it and this is the fundamental basis of the Law of Attraction.

And NOT EVERYTHING is your fault. As a psychologist, you should know that we have 65000 thoughts a day and most of them are not conscious. In that case how are you supposed to know that you were thinking so subconsciously? (SUBCONSCIOUS thoughts matter too!). In fact, LoA users use their subconscious mind as a great asset. The truth about the law of attraction is actually simple.
There is no real risk to chasing your dreams. As far as I can tell, it’s a lot of fun and a thrilling journey. My experience with countless clients over many, many years, is that all the risk…all the frustration…and all the disappointment, is born from not chasing dreams. (But please remember, there is a way to chase dreams successfully which is like chasing butterflies. Put yourself in the right energy field, and become a magnet for those butterflies. The more direct method of butterfly catching is so much harder).
The first article about this was in Psychology Today - “Throw Away Your Vision Board.” After a quarter million hits and much hate mail, I wanted to make sure that I had a thorough LOA understanding so I read every book from the originators of the law in the late 1800s and became a certified “Advanced Practitioner of the Law of Attraction” by one of the authors of "The Secret." I then wrote “Throw Away Your Vision Board 2.” This time the feedback was a little more positive. I recently published the book, Throw Away Your Vision Board: The Truth About the Law of Attraction. This article will summarize 14 reasons why there is no LOA.  
Writing your goals will not only help you get clear, but will help you create inspired action steps toward your dreams. Connecting to your "why" means connecting to the feeling that achieving the goal will give you. When we connect to the "why," we raise our vibration and become magnets for attracting the people, circumstances, etc. that will help us achieve our goal.
Before you begin to embark on the incredible journey towards true enlightenment in the Law of Attraction, it is important that you understand that you can apply it to your life and it can be effective if the correct tools are used. The practices and beliefs in this law have been igniting the lives of great individuals throughout the course of history.
