The Secret

I'm late jumping on the band wagon, but I finally broke down and bought The Secret DVD. The premise of The Secret is this... What you put out into the world will come back to you. For example, if you let off positive energy, positive things will come into your life. It's basically supports the theory of "the law of attraction." I don't know that I fully get it. I probably have to watch it again to further understand how it all works. But, I do know this.... after watching the film over the weekend, I decided to become a more positive person. That lasted about a half a day! I found myself angry at the dishwasher repair man who first told us that it was going to cost $200 to fix our dishwasher, but who then said it would be more around $300! I'd like to know how to let off positive energy in situations like this :)
