Avoid pinning the idea to a specific person, a specific house, a specific job, etc. If you are looking to manifest a relationship, define the relationship not the person you think you would like to be in the relationship with. If you are looking for a new home define the home walk through it room by room in your mind, define the characteristics of the neighborhood or climate. Let the Universe identify who the person is or what place exactly meets the characteristics you have identified. Once you have completed your definition of your dream, you have placed your order with the Universe. Surrender to the process, trust in the universal wisdom. Certainly define your dream very specifically down to the details and let go, do not try to control the: who what where when and how your dream will materialize. Your job is to define the dream and fuel it, which brings us to step 2.
Once you achieve the Theta state of mind you are guided by the program to use various techniques such as “subliminal mind commands”. This technique helps you get rid of old patterns and adopt new positive patterns. For instance, you remove negative thoughts that tell you “I am unworthy” and take up new positive patterns that otherwise help you think that “I am powerful and unique. “I am a failure” is replaced by “I can accomplish anything”.
Emmet Fox wrote about metaphysics and the power of prayer in essays and books. His teachings are founded in Christianity and bible stories. He cites Jesus Christ as being the greatest teacher of metaphysics who ever lived and explains that thoughts are our most important emanation, more important than what we say or what we do. In the books Power Through Constructive Thinking and Find and Use your Inner Power Fox speaks about "building the mental equivalent of what you want and to expunge those that you don't".
Success rate of 0.1%? Where'd you get that statistic? But whatever the actual number, your question is an invalid one. The law of gravity works 100% of the time, except we can fly planes, right? Yes, I know that sounds silly, but it's really to show you how silly YOUR question is because "LoA" works even "negatively" (put in quotations because human perception is what labels things as positive or negative when really, the universe is 'neutral' and things don't happen as a way to punish us... that's just ridiculous, it's not personal).
Some people begin to see things happen immediately, while others take a little more time. The key here is patience and persistence. As soon as doubt or fear start to creep back in, return to Step 2 and address it. If you have lost touch with your clear intention, revert to Step 1. If your belief in the Law of Attraction lags, go back to Step 3. If all else fails, repeat Step 4 every day until it becomes a reality!
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.

You are one of a kind and you have a unique spiritual fingerprint. A unique abundance DNA. The universe just wants you to recognize and own your uniqueness. Then you can have anything you want because you’ll stop doing things the way you think you should. You’ll know without blinking that you’re the best in the world at being you. And that’s more than enough to attract an extraordinary and abundant life for you and for those you love.
I decided that that goal was to make $100,000 that year. I created an image of a $100,000 dollar bill and hung it on the ceiling above my bed. Every morning I’d see the image. I’d visualize what it would be like to have $100,000. Everything I did was to achieve that goal. At the end of the year, I had made $97,000. This would never have been possible without the Law of Attraction, these visualization techniques and meditation.  
The point is, you can go through any personal development program in history. Any of the great books “The Secret” and “Think and Grow Rich”. An Anthony Robbins program. The real masters all understand the same secret. It’s not just the tools and techniques that make a difference. It’s showing people how to open a channel to abundance that really counts.

If you are new to the Law of Attraction, this book will be beneficial. You are better off reading the Masterkey which is more detailed and at least half the cost. If you are looking for new techniques like this book promised, you will be very disappointed. I also wish the author was more to the point instead of wasting pages telling you how great these techniques would be.
The Law of Attraction is a deep subject and you seem to only have a very superficial understanding of it paired with a closed mind. The reason most people aren't excellent at it is that most people have very deep seated beliefs about limits and have a lot of fearful thoughts that they pick up from society. Even babies pick up and mimic the negative moods of those around them.
It’s important to understand that mindfulness isn’t about changing anything or trying to understand it. This is because the analytical and judgement aspects — our automatic reactions — are unhealthy and actually perpetuate the problem. It reinforces the connection in our brain between the action and the negative feeling. To release that connection, approach it without judgement. Let it be.
At the end of the experiment, those who imagined they were physically younger showed signs of de-aging. Blood pressure was lowered, arthritis was diminished and even eyesight and hearing in this control group improved. By simply imagining themselves younger, some physical aging was actually reversed. Their thoughts and imagination made this happen.

"If you focus on the negative, again, you attract the lower-lying energies, and yes, you ultimately create negative. Try creating a parking space in the mall at a busy time. Focus on your space, envision it; do not allow any negative thoughts to creep into your mind, and simply stay in the positive. It may take you a few times practicing this to get it right it, but then it becomes second nature. The flip side of this as well is, psychologically speaking, if you continue to focus on something, you generally start to believe it is true, and then it ultimately will come true simply because you have followed that train of thought," Estes breaks it down.
I am trained as a "hard science" PhD in Pharmacology and do understand scientific method. The LOA is not based on scientific method and the erroneous conclusions in metaphysics are based on incorrect scientific assumptions. These assumptions may have seemed reasonable in the 1800s that there was no air around us, only ether and that thoughts only transmit through ether. Perhaps this assumption is correct, however we are not surrounded by ether.

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?
Be as clear as a laser beam. The ‘’ideal’’ effortless and conscious manifestation should look like a laser beam. Laser beam is 100% focused on one goal with all its energy and purity. We have to be certain and focused just as the laser beam is. If there is anything holding you back from believing or focusing on your goal then this something will be stopping your from manifesting your desire. I know that it’s very difficult to be crystal clear and focused but also shorter periods of time can do the magic because it brings up back to what I wrote earlier — conscious decision can create miracles. If we decide with all our will and focus then we can change an unwanted outcome into something what we want instead.
