Going with your Gut

Your feelings are a very important tool in understanding the world. Your unconscious mind does a lot of mental calculations that are more complex than your conscious mind is able to do. It can handle more information. That’s what comes back to your brain in gut feelings, hunches and intuitions. Those aren’t from nowhere. They're the result of complex calculations your brain did on an unconscious level, in conjunction with emotion.
