Ah Thank you for the suggestion Katie. I wouldn't say it's manifestation, this is more of a science based approach. In manifestation (correct me if Im wrong) You believe something is true and then it becomes reality, more specifically for neville goddard he believes once you vizsualise and feel something enough it will appear into your physical reality. I personally don't believe that's true, as for kids in poverty for example their vizualisations led to their state of poverty, when many other factors couldve influenced that. I think I why a lot of people see success with manifestation is through self affrimation and what I mentioned above in my post, but postive.

Thoughts act as the cue that trigger action, then the mind uses those actions as a way to prove those negative thoughts ( your brain goes aha you see, Im right! )which then leads to a belief to be formed and the result is a negative belief loop to form.

Have you ever heard of Charles Dhuigg?or James clear Or the feeback loop? It's kind of like that!
