There is absolutely a subconscious super-brain within our minds that we can sometimes observe and even control to an extent. It can calculate things a lot faster that we consciously do. It’s how we dream of elaborate things, it’s how we can approximate distances, it’s how our intuition works. It can be turned into your personal assistant with enough training and awareness. I believe you can become a genius if you train this part of the mind to interact with your conscious.
