Greg Kuhn wrote series of books about quantum physics and the law of attraction. In the book How Quantum Physicists Build New Beliefs, Greg Kuhn wrote a step by step easy way to trick you're subconscious into changing beliefs for the better. I highly recommend this book for anyone who has struggled with limiting beliefs.
Even if you do not believe in the law of attraction, this exercise can help you feel better about the belief or issue you want to work on. It's therapeutic to be able to let go of what makes us feel negative emotions. Even if you don't think it will change your reality it will still change your life.
The Exercise uses a Emotional Reference Chart
You identify where you are on the chart in regards to the issue and you write from that perspective, what you really feel.
Everyday you take one emotional step up on the chart and write about the issue from the new very slightly higher perspective.
Going up one emotional step in one day lets you ease your way up and feel better about the issue.
This is a rough out line of the exercise, for more information check out the links below.
