Simply put, the Law of Attraction is the ability to attract into our lives whatever we are focusing on. It is believed that regardless of age, nationality or religious belief, we are all susceptible to the laws which govern the Universe, including the Law of Attraction. It is the Law of Attraction which uses the power of the mind to translate whatever is in our thoughts and materialize them into reality. In basic terms, all thoughts turn into things eventually. If you focus on negative doom and gloom you will remain under that cloud. If you focus on positive thoughts and have goals that you aim to achieve you will find a way to achieve them with massive action.
It's curious that people who believe in a LOA are critical of those who don't and believe them to be close-minded. I have presented a lot of new data such as the erroneous science and the data showing that acting as though you had already accomplished your goals was detrimental to you doing so. Yet, LOA proponents do not look at this with an open mind and reconsider their belief system. In this way LOA is akin to a faith-based religion, except that religious beliefs can't be disproven.
