If it's any consolation, I'm pretty much in the same boat. I want/need very little. I was already that way before we adopted the D from Romania, but even though I grew up all over the world, the summer spent in Romania made me want even less than I did before. Every time we go back to volunteer in the orphanage, I get a fresh inoculation against consumerism. I truly believe that as you accumulate more and more, the tables start turning and you find that your possessions start to own you rather than the other way around.
My W, OTOH, is a consumer. For my entire married life, we’ve lived paycheck to paycheck. Before we had kids, I was knocking down $160K plus per year and we were still broke when payday rolled around.
