I love the story of Gandhi and the reporter.  Gandhi was giving train stop talks.  The train would stop, a crowd would gather, Gandhi would talk to crowd from the back of the train, then the train would chug away.  After one stop, with the train slowly and loudly chugging away and Gandhi still standing at the back of the train -- I can imagine his knuckles holding the railing, the clouds of coal burning smoke permeating the air -- a reporter runs behind the train as it starts to pick up speed.  The reporter calls out, "Do you have a message for the people?"  Gandhi answers, "My life is my message!"

That is true for us all.  Your life is your message.

(I originally read this story in "Your Life is Your Message" by Eknath Easwaran.)
