I think I'm led by spirit. I think I'm led by a sense of what is right and what feels good to me - what I accept, what is joyful, what is positive. I see my mission, in a way, as carrying that forward - not so much by preaching, but by embodiment.
If you can look back and say, "The economy's better. Our security's better. The environment's better. Our kids' education is better," if you can say that you've made things better, then considering all the challenges out there, you should feel good. But I'm the first to acknowledge that I did not crack the code in terms of reducing this partisan fever.
