            Are You Willing?

      Are you willing to forget
      what you have done for other people,
      and to remember what other people
      have done for you;
      to ignore what the world owes you,
      and to think what you owe the world;
      to own that probably the only good reason
      for your existence is not
      what you are going to get out of life,
      but what you are going to give to life;
      to close your book
      of complaints against the management
      of the universe,
      and to look around you for a place
      where you can sow a
      few seeds of happiness --
      are you willing to do these things even for a day?
