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.
3) The Third List: Your Gifts. The third list is, in my opinion, the most important one. Your soul mate will not be coming into your life to rescue you, make you happy, or save your life. A soul mate is a friend and partner with whom you’ll be sharing your life. Someone who will love, nurture and support you while you love, nurture and support them.

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).
People living today have the same access to the original creators' texts online as people in 1880 had in printed books. It's exactly the same material. You're essentially arguing against yourself because asserting that no one knows for sure about it would have to apply to the people in 1880 as well. Your argument is an appeal to ignorance, which is a logical fallacy. The text in the creators' books is precisely the data he's referring to, a intellectual creation that has absolutely no scientific basis.
How is that one person is willing to do all that it takes to reach their goals, while another person gives in to silent resignation at the first sign of resistance? Why is one person willing to sacrifice nearly everything in order to live the life of their dreams, while others are too afraid to take the next step in fear of suffering through a catastrophic failure or embarrassment?
