Three years in and our ‘self-sufficiency’ is limited to about 3 weeks of food per year if we relied on our own garden/forest 100% of the time for those 3 weeks. We don’t do that, but instead supplement with the garden and forest and learn more each year about what does well in our little spot.
I don’t say this to dissuade - but to make sure you set proper expectations. Self-sufficiency, even just for food, is a decade-long endeavor where you almost certainly will have to work some kind of job or have some income in the meantime.
