It's All Relative

I think I can, I think I can...

After my Mom's and Oprah's insistance, I picked up this book at Costco the other day. Apparently it's the key to my success and happiness.

Basically it claims that anything you desire can be achieved and attained through the power of attraction. The idea is that you must think positively, sending out "waves of attraction" focusing on the thing you want, whatever that may be. Accordingly, the universe will send to you what you put out. After reading it, I must say it's a fascinating book, with a lot of good messages on visualizing your goals until they become reality, but I'm confused on the logistics of some of the teachings. For example, the book encompases all areas of life that can seem frustrating to us, particularly love. However, it sticks to the idea that if you believe it, you can acheive it. But my question is this: if I really want to date Andy Roddick, I can't just think about it all day long and expect Andy to just one day knock on my door and then live happily ever after, right? I mean if we are talking about the Laws of Attraction, doesn't that require the other's simliar energy too? How do they explain that? Just because I am visualizing Andy Roddick as my boyfriend, doesn't mean he's thinking about me as his girlfriend so doesn't that distrupt the whole theory? Maybe I'm missing something here...
