Is it possible to know everything ?

Have a look at:
conscious competence learning model matrix- unconscious incompetence to unconscious competence

unconscious competence

• the skill becomes so practised that it enters the unconscious parts of the brain - it becomes 'second nature'
• common examples are driving, sports activities, typing, manual dexterity tasks, listening and communicating
• it becomes possible for certain skills to be performed while doing something else, for example, knitting while reading a book
• the person might now be able to teach others in the skill concerned, although after some time of being unconsciously competent the person might actually have difficulty in explaining exactly how they do it - the skill has become largely instinctual
• this arguably gives rise to the need for long-standing unconscious competence to be checked periodically against new standards
