One of my favorite poems :)

O Me! O life!... of the questions of these recurring;   
Of the endless trains of the faithless—of cities fill’d with the foolish;   
Of myself forever reproaching myself, (for who more foolish than I, and who  more faithless?)   
Of eyes that vainly crave the light—of the objects mean—of the struggle ever renew’d;   
Of the poor results of all—of the plodding and sordid crowds I see around me;          
Of the empty and useless years of the rest—with the rest me intertwined;   
The question, O me! so sad, recurring—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 will contribute a verse.
