Back in the dark ages, when I was living on a CAL 20, I went to a lecture by Herman Daly who really blew my mind with his thoughts on economic growth. Sadly. he passed away recently.
I mention this here because his take on economics has a whole lot to do with my thoughts on living within a finite resource envelope, growth for growth's sake, and the process of swimming against the prevailing current.
I'm pretty sure that if I had not found myself in a economics lecture all those years ago I'd be going along with the great unwashed hordes thinking that one can buy one's own slice of happiness by spending more for a bigger boat. Which makes Daly one of my major influences in terms of boat mindset.
I'd seriously check out some of his books and lectures if you have the chance.
