Funny thing is when you experience similar reoccuring problems in your relationships with other women it's like a wake up call, it's like you kind of say, hey all those relationship gurus are right, it's not the same woman but it's the same problem. Then the power comes because you know that if you change you, you can change your relationships with others.
I think it works by expectations and beliefs, what you believe about how you interact or relate, and what you expect from others for your actions.
