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.
And they'll try to use the "LoA" as a way to get more 'things' which really just satisfies ones ego and comes from a place of lack. They use it as a tool, as a means to an end. But it's not a tool, it's more of a "this is how it works" and being consciously aware of how it works can be pretty powerful, just not *necessarily* in the way many would think (red lamborghinis and such).
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.
Create a list of what you can do now to fulfill your goal. Looking on search engines and authoritative sites is an excellent way to help you come up with ideas for your list. Read forums and articles since there is a good chance there are others that have the same goals and more than likely has taken the time to write about their experience. Once you have your list, get to work and keep pushing until your goal is realized.
