Michael Losier is the best on the law of attraction issue. He teaches one exactly how to master the art of "believe". It is easy to tell people that the law of attraction works; however, the LOA works if one firmly believes in receiving something specific. Now what if one can not convince oneself to deeply believe? Michael has a whole chapter on how one can realistically think ones desire into reality.
Many sweepers swear that they have increased their luck by wearing a favorite pair of socks or t-shirt as they enter sweepstakes or by having lucky symbols like four-leafed clovers, ladybugs, or even Troll dolls near their computers while they enter. Still, others perform some kind of lucky rituals before they start their daily sweepstakes or listen to lucky music. But this is superstitious nonsense, right?
Turn your bad luck into good luck. Lucky people see the positive side of their bad luck. They do not dwell on their ill fortune. They embrace failure and view it as an opportunity to learn and grow. Lucky people usually are more resilient when bad things happen to them. They believe that good things will happen and avoid dwelling on negative things.
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 work of quantum physicists during recent years has helped to shine greater light on the incredible impact that the power of the mind has on our lives and the universe in general. The more that this idea is explored by scientists and great thinkers alike, the greater an understanding we have on just how significant a role the mind plays in shaping our lives and the world around us.
