It's not about pick up and relationships. It's pseudo-intellectual new-age bullshit about you making your own reality. You think thoughts and the universe re-orders itself to your desired outcome. You want something and the "law of attraction" re-orders the universe to give you that thing. It has nothing to do with motivating you- you just want something really bad, wait for it, and it comes to you. It's complete bullshit. Do you think the starving kid in Africa doesn't envision herself enjoying a big meal? Do you think the amputee doesn't want a new limb?
Don't get me wrong- having a positive attitude can have an effect on your life, but it's because it motivates you to go out and make things happen- not because your thoughts re-order the universe.
