4) Hmm... weird again. Dunno what books you've read, but that is totally false. Nothing is perfect and the "LoA" I subscribe to doesn't say what you've described. Visualizing is only one tool of LoA... one which I don't really use. The perfect relationship and perfect diet are total BS. you don't visualize those things, you either build them (a good healthy relationship, not a perfect one) or follow them (a good diet).
The law of attraction (LOA) is the belief that the universe creates and provides for you that which your thoughts are focused on. It is believed by many to be a universal law by which “Like Always Attracts like.” The results of positive thoughts are always positive consequences. The same holds true for negative thoughts always leading to bad outcomes. But the LOA is much more than generalizations; thinking about red Lamborghinis will bring you red Lamborghinis – always. To the believers, questioning the validity of the LOA is akin to heresy and blasphemy; it creates religious fervor. To the uninitiated, it may seem silly to discuss even the possibility that such a law could exist.

It’s quite clear that success has nothing to do with our initial set of circumstances. Some of the most poor and disadvantaged people in the world have achieved the greatest successes of all time. Oprah Winfrey was born to a single mother on welfare and was physically and sexually abused as a child. J.K. Rowling was divorced, had a daughter, and was living on government assistance before publishing the first book in the Harry Potter series.
