Please open up your mind! This is one way to be more intelligent.
If you keep an open mind, what new information that comes your way would not be rejected outright. Your mind will withhold any kind of judgement or criticism or analysis. It stands neutral and takes in things as “what is”, not what you think ought to be.
Without imposing restraint and constraint on this new information, the data would then gets through to the other side of the mind – the subconscious mind.
The subconscious mind will take over the duties and act upon it.
