Minimalism (aka Simple Living) is a great way to live an ecologically-sustainable life, but is there a way to make it sustainable from a pysochological standpoint as well? That is, how does one reduces one's feeling of deprivation while reducing one's material possessions?
Don't know if it'll work for everyone, but my solution - and indeed, the way I arrived at living a (somewhat and in some respects) minimalist lifestyle - is to not think of things as deprivations, but as advantages. So my not owning a TV is not depriving me of TV viewing, it's giving me lots of free time to do other (IMHO more interesting) things; not flying commercial is not deprivation of travel, but frees me from TSA indignities & seating discomfort; driving a small car gives me agility rather than depriving me of comfort & status; biking instead of driving gives me healthy exercise & recreation...
I believe the key lies in refining the few things that you decide to keep.
Such an approach is described at less.best.
