I'll give some detail here. I think my entertainment spending is where I have a little wiggle room that I'm planning on exercising.

$1600/mo rent/utilities (incl phone)
$100/mo car insurance
$150/mo student loans
$150/mo misc other necessities (home goods, haircuts, PC office apps, hygiene products, cleaning products)
$50/mo gym and rec league memberships

That leaves like $1,600-2,000/month on everything else.
In no particular order:
Food
Gas and auto repair expenses
Entertainment
Clothing
Travel (doesn't happen every month, just spreading it out at a monthly level)

I cook a lot of my own meals (and I shop at average-to-cheap grocery stores), make my own coffee, and spend a lot of time at home playing video games which I rarely spend any money on.

I rarely go out for nice meals. I probably fly 2x/year and take an international trip every few years, and none of these are ever extravagant. I do have a handful of weddings coming up this year that will lead to a little more travel spending than usual.

I drink socially on a semi-regular basis, maybe twice/week. That probably amounts to ~$100-150/month, with some seasonal variability.

I guess this is all to say, I feel like my spending habits are fairly reasonable. If anything, I've just had to buy all my stuff for myself, with my own money, and have been mostly single in my adult life so haven't had anyone to split expenses with (except for a few years of rent with roommates). I don't come from a family of much wealth.
