I just came from the Law of Attraction Seminar by Michael Losier. I would recommend that you get his books if you are in any way interested in attracting more positive things into your life.
Michael has many good tools to use but the one that sticks in my mind the most is the “Don’t, Not and No” rule. Eliminate these three words out of your vocabulary because they are attracting the negative into your life.
Instead of thinking about what you “Don’t” want, think about what you do want. The Law of Attraction is that you will get what you think about so watch your words and be positive.
