We don't read and write poetry because it's cute,We read and write poetry because we are members of the human race，And the human race is filled with passion，Medicine,law,business,engineering,these are noble pursuits and necessary to sustain life，But poetry...beauty,romance,love...these are what we stay alive for，To quote from Whitman,“O me，O life， of the questions of these recurring，of the endless trains of the faithless，of cities filled with the foolish，what good amid these,O me,O life?”Answer.That you are here,that life exists and identity,that the powerful play goes on and you may contribute a verse， That the powerful play goes on and you may contribute a verse.

The only person you should try to be better than is the person you were yesterday.
