The most powerfilled state is when you start living a through me life. And you can’t do that if you just keep make it about you, feeling lack. Start living for your purpose, to help others, and to give. Yes, you can still want the Audi R8 and collection of motorcycles like I do. But those are just things and they won’t truly make you happy. “Things” will be the by product of living a purpose filled life.
What do you want? What are your goals, wishes, and dreams? Get really clear about what it is that you want to manifest in your life. Do this in your quiet space. I encourage you to write it on paper with a pen. Describe what it looks like, draw it, define it. Make sure you stay with the positive attributes of your vision and define them specifically. Creating a manifestation/vision board is a great tool to help you visualize your goals and dreams.
You claim that "positive thoughts always resulting in positive things" is not the basis of the LOA. In part you are correct. The foundational basis in science, as I alluded to in the article was that thought stuff particles travel through ether (not air) and interact with formless stuff to create whatever it is that you are thinking about. This was how "the law" started.
