Do you ever wonder why you don’t get more done than you do?  Perhaps there is a reason for it.  Dr. Catherine Morris Cox, the American psychologist known for her work on intelligence and genius, suggested that geniuses are not produced by great intelligence alone, but by some factors that can be developed by the average person.  Concentration is one of those factors.  Dr. Cox’s study revealed that some of the world's greatest geniuses were not necessarily intellectual giants, but those who had the power of concentration, even though they were greatly distracted.
