I'm posting this to help a friend. The following article explains (in part) why I no longer subscribe to the Law of Attraction (focusing on the positive, denying the negative, etc.).
I read a better (easier-to-understand) article on this subject, but I can't find it at the moment, so in the meantime, here's this one.
For anyone who has tried without success, believing that if you could only think more positively or have more faith in the process that you'll finally manifest your dreams, you can stop beating yourself up. It's not you.
