You're talking about two completely different concepts.
Getting enthusiastic about frugality is one thing.
Feeling like you have to put off being happy today and live for an idealized future is another, highly problematic way to think and live.
Go ahead and get super into frugality, but do not conceptualize it as some.kind of self-denial.
When done properly, good frugality should make your life better, not worse. It's not about what you can't or shouldn't spend on, it's about finding creative ways to get sooooo much more out of every dollar you do spend.
For me, it's not depriving myself of exoe dive restaurant dinners. It's the fun of trying out a new recipe at home, putting it all together, taking a gorgeous bike ride with my partner to a beautiful location, having a picnic, and having a far better time together than we would at a restaurant.
It's me learning to tailor my own clothes, so now clothing shopping is cheap and easy, because I can just make everything fit perfectly. I can buy a $3 shirt from a thrift shop and make it look like an exquisitely tailored designer piece instead of shopping for hours trying to find something flattering.
It's getting really into long walks and audiobooks. It's giving up my high maintenance hairstyle and fussy makeup and enjoying the freedom of a 5 minute morning routine. It's having games nights with friends. Going to tons of cheap/free community events. Making fresh bread, tortillas, humus, etc, all of which are a billion times better than expensive store brands.
It's not about being cheap, it's about becoming a major snob about spending. Where every dollar needs to pull it's weight in your world.
It's not about holding out for some perfect future where you will finally buy your happiness on the blood sweat and suffering of your working years. It's claiming a better life NOW.
If frugality isn't making you happier, fitter, healthier, and more interesting, then it sounds like you're doing it wrong.
