Pick small achievable goals, and achieve them. We can take small slices off the beast, or we can celebrate small victories. Anything else is gunning the engine in neutral. Choice is powerful, as you say. So is asking questions.
Questions focus awareness, and get the mind working on solutions.
One of my favorite peace activities is a form of circle dance. Every indigenous culture I've run across had one, in some form. It is a great way to express community, and ground out kinesthetic energy that might otherwise lead to violence. The creator had a vision of people all over the world dancing and eating together, across national, religious, cultural, and ethnic lines. I'm working with a virtual university, which will have accredited programs so that people in 3rd world countries, and even our own inner cities, can get their degrees solving problems locally.
