I lived more or less that way until age 30. But then as my income rose dramatically, my lifestyle gradually grew in cost as well. But I don't think that cost is truly buying me more fun. I had a ton of fun in my younger years on a lot less income.

And as I've put in the effort to be more mindful of my spending, it's felt more liberating than anything else. All this to say, you might also find it can actually feel better to do other things with money than spending it.
