Toward Ecosophy

I've been reading your Encyclopedia of Natural Magic, and find that I get stuck on step 1, choosing the purpose for the working. The general protection amulet from the FAQ seems clearly useful regardless of my elemental balance. But one of the things I've found very helpful about the CGD work is that I don't have to already know what I'm lacking or in what direction I need to go to improve and balance myself. And natural magic seems not to have that feature. Do you have any suggestions for how to suss out a good purpose, or perhaps recommendations for other general purpose beneficial workings?
