It works extremely well for me. I've been able to manifest my apartment, body, face, and income. Using the power of your mind is all you need. To put it simply, 2 weeks ago you created the reality you live in now. Momentum is real, inspired action is real, and any method that works for you is the 'method'; it's real. Meditate on your questions, usually the answer comes from within.
Old topic, but I've known about the LoAs for a while now (around 3+ years?). Read a bit from him and watched multiple Youtubers summarize the law, and I've been able to manifest a few things, mainly money and physical appearance changes.
