I've been spending less every year that goes by. The only time I spend money is when I go out, so I moved into a house that I like to stay in, and go out far less not because I'm trying to cut down, but because going out doesn't interest me as much anymore.
I cook at home by choice, get occasional restaurant food delivery, and get girls delivered as well for 1,000-1.200 baht total.
Life is good.
