I guess my PoV is that saving $2k+ a year is nice, but not significant if that's still only ~2 months rent. It's better - much better than it being 1 month's rent - but to me, you have to focus on the expenses that are the biggest and are most likely to grow. You can definitely save a lot of money by chipping away at the tinier stuff, but if that's not growing, I'm not sure it buys you much.

I suppose from another point of view, it's better to start with the small things you have control over, and make some tiny but measurable improvements, so you don't despair at how big everything is. That's fair.
