The other common
answer you'll hear for "Where do I start?" is "At the door step." It's especially helpful to think this way for zone designing.
But first, as mentioned, before making that initial step outside, in the
permaculture design process it's important to think about your own personal long term goals and objectives, and your needs and desires; and also consider your capabilities and assets.
Additionally, having buy-in really helps. Consider who else may be your "client" to serve? Family? Friends? Community? Critters? They can be your "cheerleaders" to help make progress and share in small successes. Get them involved to help defeat the blues.
I personally like to have a (digital) document via Google Docs, listing mission, vision, and long, medium, and short-term goals, as well as unique personal challenges and characteristics. A notebook would work too, of course.
Parallel to your "people analysis" is the "land analysis" and then assessment and design, and then the "doing" part.
How well do you know your land over the seasons? The
permaculture principle to "observe and interact" comes into play, here. In my digital document, I list as many nuances and observations from being on the property as I can.
Where does the sun hit the land in winter? What is the average rainfall? Where do I need more privacy? Where is the soil best/worst? What animals pass through? Best access? Sunny slope? Yada yada yada. Just a big ol' document of observations.
The PaDM in Chapter 3 lists several
Permaculture design methods to choose from after you know what you're working with. Map overlays, random assembly, component characteristic matching, zone and sector design, and flow diagrams are all examples.
The fact that you have a home plus land is fantastic! Something to be proud of.
And even if you feel like you aren't "doing" anything in the moment, sometimes that can be the best thing, you know? Simply observing and thinking while letting the land express itself... that's still progress.
