provided that genius involves then some sence of creativity as opposed to the ability to erudite knowledge for a test(IQ)
and that obsession also has nothing to do with taking the same test (unless your obsession of course was the test)
obsession does not equal creativity, for the obsessed may not indeed be creative, nor conversly the creative be obsessed
or perhaps what makes genius is a far more complex ideal than what we can define
perhaps its more a combination of disipline and cunning?
