At birth you come with or carry a lot of beliefs, and behaviour baggage. Much of them simply slow you down, they reduce your performance and even build your stress and you have little or no idea that it is all happening.
These are neuro or subconscious thinking patterns that get in the way of your best or high performance.
Some of these came in your DNA package at birth and some you added intentionally also many others sort of snuck in through the back door without you noticing.
There are are some beliefs and values that are subconscious and like Trojan horse viruses attacking your computer. These belief and performance mal-functions get through your intelligent thinking defences while you are usually occupied with other emotional matters.
