Once asked about advancing world peace, the Dalai Lama first responded by asking
"What is world peace?" and answered himself, "It is the total sum of all the peace in the hearts of all the people in the world. That is world peace"
So there is something I can do today to truly, specifically and personally advance world peace: it is to be peaceful. To set aside as much as I am able ill will; to not argue with my partner, but to do as she requests.
Certainly there are other ways to advance world peace, but for me there is no greater memorial to death by violence, that a day of peace. And no greater way to contribute to a day of peace, than by being peaceful.
It may not be easy: irritation, frustration, impatience all arise unbidden. But for the lives of a million dead, I vow to set my heart and mind to the task.
May we be at peace.
