You HAVE to rebel(think out of the box) in order to create something.
AFTER you've created it, however, that which you have created can become the norm..
and thereafter, if another wishes to improve upon your creation, they too would have to rebel against it.
Certain things may never be improved upon.. like Newtons Theories of Motion.. HE was thought to be a rebel to think up those theories.. but now we all accept it as the norm.
