I've recently completed a course in Permaculture, and am eager to put the principles to work. My hurdles so far are not the hardiness zone 3a climate but getting over my own upbringing about what a garden should look like (you know, everything straight and trimmed just-so, no "weeds"). I look at the healthy green chaos around me, full of hard-working, soil-remediating plants, and am grateful that Mom can't see the "mess"! Another hurdle is remembering the virtue of patience, and not wanting everything right now. (If I had everything right now already, I would not have had time to learn how to incorporate it!) A third hurdle is learning not to rely on what people have already done, because I can't find much that directly applies for this location. Ah, pioneering, sort of! My goal is a food forest to feed myself and to have extra for the community, possibly as a cooperative venture, as there are people expressing interest at present. I am also expanding my definition of food, and coming to appreciate native and adventitious edibles.
