It's my job to do it. Applying permaculture to homesteading creates very efficient systems. If I'm spending my time doing one thing I'm often getting secondary and terciary yeilds. When I muck out the horse paddock I'm feeding my chickens, making compost and doing fly control all at once. There are many examples. But the key principles I use in almost every system are integrate rather than segregate, obtain a yeild (in more than one form of capital), catch and store energy, and observe and interact with nature.
