Yeah, we never equate "simple" with "easy". We meant it more in the way of "uncomplicated". City life was so full of distractions, busyness, and dependence that it was impossible to live simply.
And your goal sounds pretty awesome. We will probably build an earthship-style house here. Not enough land for others, really, but it is good enough for us!
Let me know if you have any ideas for collaboration.
Keep me posted on your journey and I will do likewise.
All the best!
