A table could be a stool
Do you want to live in a mental world of "could be's"?
Or, would you prefer to live in a world of "is"?
Broadly stated, the difference between an average person and a genius is the degree of specific knowledge brought to bear on any particular subject.
The average person can operate off of a broad base of information that is wide and shallow without stepping off the edge of the universe. However, the genius has a depth to the base of general information that takes it several steps deeper into a real understanding.
Or, put another way...
If you had to have a doctor operate on you, would you want the doctor who graduated at the top of his class or the one who was near the bottom?
There are degrees of everything we know. Most people do not care about the details, the specificities and the inner connectedness of information. The genius will not settle for less.
We can't choose to be a genius, certainly. But, we can all increase the depth of our understanding. We can endeavor to trade up from okay to good and from good to better and from better to best IF WE SO CHOOSE.
What kind of thinking each of us does is a matter reflecting who we are and what we are made of. No less so our confusing a table with a stool and seeing little importance in the difference. :)
