"At every moment in every person’s life there is work to be done, always work to be done, some of it small, some of it Great. The Great Work, in a sense, always has to do with healing the world, changing the world, and, as a necessary predicate to that, understanding the world. You rise every morning aware that you are called to this work. You won’t live to see it finished. But if you can’t hear it calling, you aren’t listening hard enough. It’s always calling, sometimes in a big voice, sometimes in a quiet voice. "
