Recycle paper, plastic, metals. The amount of trash you throw away is an indicator of your progress in this journey. Get in better physical shape. If you're using less energy, you will probably be doing more labor and being more active. But don't wait until year 3 either.
Gardening is a good way to start.
Year Two 1. Continue whatever is left from the year one agenda. Tell your friends and family not to bring any plastic or paper trash into your house. If they bring something in, they have to take it with them when they go. Install a solar hot water system.
