I’ve done this various times over the years. Although I always had car, I mostly traveled by bicycle and my wife had her car. Now that the kids are grown up and moved out, the wife has passed and I mostly work from home, I’m back to walking a lot again. I now remember how much I enjoyed it. It slows the pace of life down. I’ve also greatly simplified my diet and that reduction of choice has made my life more enjoyable too. I lean more and more to a minimalist lifestyle every day.
I applaud you, I think it’s a choice a whole lot more people should make.
