To attract what it is you want, you have to have a high vibration level, in other words, be happy and joyful. The higher your vibrations, the more joyful and happy you are, the more likely the universe will receive your signals. To accomplish this task, take at least 15 minutes out of your day to do something that brings you joy. The better your mood, the better the outcome of the manifesting process.
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.
