My Three New Goals

I have been doing a lot of thinking lately. My ex-husband's family and the non-profit they started do quite a bit of work with the poor and hungry in the West Indies. We all know of other groups that help people around the world. It seems to me, though, that there are not enough groups helping out here at home. I am interested in advocating and/or working with/for certain causes:

1. The poor/hungry/homeless here in the United States;
2. Immigrants to the United States;
3. The mentally ill.

Any ideas/insights/advice you may have would be most welcome!!!
