Who are they?
People who have creative minds and think beyond what is deemed as the norm. Those who have an ability to move the world from a status quo - scientists, leaders and philosophers. Or, those who have an unique and special talent or ideas which sets them apart from the rest of the millieu - artists, architects, writers etc. Including people who have made a difference to their community and the world at large, knowingly or unknowingly so.
The big Q though is - Can every human brain be trained to reach this potential or is it something more innate? Nurture or Nature? Or could it maybe a balanced mix of both?
