I actually have a copy of Gaia's Garden, but it was a workshop that I attended on permaculture principles that really started making sense to me. The instructor was talking about thinking of your home (your life) in zones, circles radiating out from the center. The things that need your attention the most should be close, and so on from there. Now, you'd think that we'd all already understand that. It seems like common sense, but the way that my instructor explained it made me see that I wasn't doing that quite so well, neither in my garden areas nor in my life. It blew me away.
