“That you are here—that life exists and identity,That the powerful play goes on, and you may contribute a verse. What will your verse be?”So concludes the iPad commercial featuring Robin Williams’ voice from The Dead Poets’ Society quoting Whitman’s masterpiece O me! O life! I still watch that ad from time to time, and it still stirs something inside me.My contribution to the powerful play? Creating messages that make a difference and spread light through humanity.
