The most successful people today are those who continually invest in learning and expanding their intellectual asset base. They are wide open to new ideas and new approaches.
A major mistake that people make, especially, those who have graduated from the university, is that they conclude that everything they know at the moment is all that they need to know about a particular subject. This is called “intelligence trap” of the poor performer, the unconscious incompetent.
This is a person who does not know, and does not know that he does not know. The person cannot be helped, because he is closed to new information. This is why beginning of all wisdom is often the awareness of how ignorant you really are.
