We are definitely not cut out for keeping our expenses at $25k/year. I know this is an uncommon position in the MMM world, but I think frugality is not a binary value, and our own attempts at gravitating away from the more typical consumerist American lifestyle to be worthwhile still. We have some hobbies that we really love, including mountain biking, skiing, and travel, that add richness to our lives -as well as to our budgets. Our DDs play fancy violins in fancy youth symphonies, enjoy some kid sports and summer camps, and love doing these activities. We're not FI yet (though closer every day!), though I would be with lower baseline expenses. But my RE will be more meaningful and exciting for me if I wait and build a little more. Which is convenient, as I still like my employer and my work.
I could defend my position more by describing all the ways we don't spend money like people in our peer groups locally (family, professional, kids' school friends), such as older, cheaper house than we could "afford", older cars, no cable, etc., but I think getting hung up on those details isn't as important as figuring out what priorities represent value to us. No shame, we're doing our best.
