A woman of color refused to ride in the back of the bus and it began a revolution. Rosa Parks was not initially part of a movement, but her act of courage enabled a nation to face years of injustice. We always think that greatness and significant change comes from collective courage and planning, but sometimes it only takes one person. We may not launch a memorable social change but the power of one resides in each of us. Today the world will offer opportunities for change. For some it will be the chance to support any attempt to lessen violence in our towns and cities. For others it will be the struggle for better schools, housing or health care for the marginalized. The opportunities are without limit, and the power of one remains ready to be unleashed.
