If man understood that "what I create has nothing to do with what anybody else is creating" then he wouldn't be so afraid of what others are doing.
You are the only one who creates in your experience - no one else. Everything that comes to you comes by the power of your thought. If there are changes you would like to make, it will be of great value to begin telling a different story - not only about your body, but about all subjects that have been troubling to you. As you begin to positively focus, getting to feel so good about so many subjects, you will begin to feel the power that creates worlds flowing through you.
If your dominant intent is to feel joy while you are doing the work, your triad of intentions - freedom, growth and joy - will come quickly and easily into alignment. See your "career" as one of creating a joyful life experience. You are not a creator of things or a regurgitator of what someone else has created or a gatherer of stuff. You are a creator, and the subject of your creation is your joyful life experience. That is your mission. That is your quest. That is why you are here.
