Simon says

Greatness, in the last analysis, is largely bravery--courage in escaping from old ideas and old standards and respectable ways of doing things.   This is one of the chief elements in what we vaguely call capacity.  If you do not dare differ from your associates and teachers you will never be great or your life sublime.  You may be the happier as a result, or you may be miserable.  Each of us is great insofar as we perceive and act on the infinite possibilities which lie undiscovered and unrecognized about us.
