Well, for starters, there's a little thing called karma. If you're trying to manifest a relationship with someone but it’s not supposed to happen because someone better is down the road, it's not going to happen -- no matter how many times you "feel it real."
And for another, there's a big thing called conditioning. Many of us have been conditioned to revert back to negative thinking. Think of common phrases we all use such as “You can’t have your cake and eat it too.” Why would you want cake if you can’t eat it? Or “Don’t trade the devil you know for the one you don’t” and then there’s, “Don’t bite the hand that feeds you.” All of this negative conditioning is designed to keep us stuck.
But there are three great things you begin doing now to change negative conditioning and make the Law of Attraction work for you.
