I have always been a very trusting individual and possibly too much so. But I would rather be trusting than skeptical. I have mentioned a couple of Applied Kinesiology (AK) but there is a process I learned at an event I attended in Phoenix.
I discovered Intuitive Awareness (IA), the rubbing of fingers together to develop a base point of yes and no was more accurate and could not be influenced by the subconscious mind.
Currently I use IA to know when to work with someone, when to avoid someone or something. It is a great leveler. It helps to know ahead of time if I should trust someone or avoid them altogether.
