I spend a lot more than I used to, and don't regard myself as terribly frugal any more, but strictly speaking I suppose am still LBYM since I spend less than FIRECalc says I could spend.
I save the most by staying at home a lot. I am kind of a homebody and enjoy it. So anyway, this means:
(1) I don't travel (which can be insanely expensive, and doesn't float my boat). Every day I thank the heavens above that I don't have to travel for work any more at all, now that I am retired. And travel for pleasure? Pffft. Yeah right, what a drag. If I'm curious about other regions, that's what Google maps/Streetview is for. I know, I know, I'm hopeless. I suppose that I just don't have the travel bug.
(2) No boats, airplanes, RV's, etc. This is a corollary to (1) above. No sense in spending a lot of money on expensive vehicles to enhance my traveling experience but not my usual life day in and day out.
(3) No concerts or events. This works out well for us since we do not like crowds and honestly prefer staying home and listening to youtube.
To me, it is important to do some introspection, figure out what it is that you really, really want, and prioritize. I get more value for my money this way. So often we think we want something because, well, everybody else does, and we SHOULD want it, right? I am not inclined to bend to this sort of pressure, although sometimes I stumble due to being far from perfect.
