Law of attraction practiced prior to the 1800s. If you are referring to arcane practices in Babylon and Biblical times that we have little knowledge of, I am aware and have looked at these. If there are some specific and relevant references I would be interested in hearing them. As you believe in a LOA, most of what you hear will be filtered through this lens. As I now do not, most of what I hear will be seen through that lens.
The fact that we build evidence to support our beliefs is not evidence that a law of attraction exists. Why do innocent babies attract negativity that causes them to be in the ICU with fatal illnesses? Why do happy children get hit by cars or murdered by terrorists? Why do people who cheat and lie and abuse others, sometimes prosper and become leaders in society? If we are using anecdotal evidence to support claims, I will have plenty of examples.

Napoleon Hill published two books on the theme. The first, The Law of Success in 16 Lessons (1928), directly and repeatedly references the Law of Attraction and proposes that it operates by use of radio waves transmitted by the brain. The second, Think and Grow Rich (1937), went on to sell 100 million copies by 2015.[60] Hill insisted on the importance of controlling one's own thoughts in order to achieve success, as well as the energy that thoughts have and their ability to attract other thoughts. He mentions a "secret" to success and promises to indirectly describe it at least once in every chapter. It is never named and he says that discovering it on one's own is far more beneficial. Many people have argued over what it[61] actually is, some claim it's the Law of Attraction. Hill states the "secret" is mentioned no fewer than a hundred times, yet reference to "attract" is used less than 30 times in the text. He further claims that people can obtain what they desire through thought of definite purpose.[62]
So, if you have a big goal that you want to someday achieve, you have to start by giving it your energy and attention. Canfield recommends going a step further, and acting as if you are already where you one day want to be. That way, you are already embodying the success you want to have, and you will use the law of attraction to reach your goals more quickly.
And, just as an important side note: Your subconscious is way, way more powerful than you possibly give it credit for. Most people don’t realize this fact. Your subconscious knows exactly what you’re going to do. It’s infinitely more aware of what’s happening in the universe than your conscious mind. It simply won’t be bullied. It’s happy for you to tell it what to do, once you master the process of doing so.

Imagine you’re having a dream. In that dream what exactly are YOU? Are YOU the physical dream character you identify with? No, of course not — that’s just your dream avatar. YOU are the dreamer. The entire dream occurs within your consciousness. All dream characters are projections of your dream thoughts, including your avatar. In fact, if you learn lucid dreaming, you can even switch avatars in your dream by possessing another character. In a lucid dream, you can do anything you believe you can.

The 3% of the class that had both set written goals and created plans, were earning, on average, ten times as much as the other 97% of the class. Yes. You read that correctly. 10 times as much. This is an extraordinary difference. And other, more recent studies, have confirmed the same notion that you must set written goals with detailed plans if you want to succeed in life.
