I obviously have not read every post in this thread, but I have always lived frugally out of necessity.
I work for a school district and get paid once per month, so I do grocery shopping once a month, with maybe a few perishable items restocked at the 2-week point.
The nearest supermarket (or convenience store, gas station, etc.) is 15 miles from home, so it makes sense to consolidate trips. I don't need fancy toys or new vehicles. Every vehicle I have bought in the past 25 years I have paid cash for. If they break, I fix them myself. The only debt I have is the mortgage. No credit cards. If I can't pay cash for it, I don't need it.
No cable TV here, I tried satellite but dropped it because of the junk I don't care to watch. I get 3-4 channels via antenna, which is plenty.
Even if I had a lot of money to spend, I don't think I would live any differently.
