Also, you don't 'attract' anything, it is always there as a possibility. At any one time there are both nice and mean people on the street, if you believe either, then you will meet that one - the other is still there but you never noticed and walk right past that guy.
So if anything the lesson is life is wide open with possibilities, perceving them is most of the battle. Or at any time the world exists infinite objects positive or negative in nature, you just have to go get it, albeit subject to the constraint of knowledge of how to achieve that. (Like you can't fly a plane without ever taking lessons, but you would be surprised how much of the 'foundation' you already know which are basic life skills, so in an emercency scenario you could probably pull it off with a little assistance.)
