Most people stumble from the very beginning by not knowing precisely what it is they want. How can you manifest something in your life if you don’t know what it is? Example, you want a new car. O.K., what kind of car? What colour is it? What body style, make, model and options do you want and what price range? Without tailoring your desire to specific details, how is the universe going to know what you want when you don’t know yourself?
From the moment we’re born, every single one of us receives societal programming: parental, media, peer. Very few of us have a true idea of what our authentic essence is and what it truly desires to thrive. Manifesting starts with taking deep inventory of that programming we’re raised with, then getting into your authentic essence and asking yourself what you truly want—and, finally, breaking the mold of what limits you from achieving that.
