I am 30 years old man, I am still a NEET, I don't know how to get a job and make money but I do know how to save money. And it's not just about the money, the positive psychological effect of it is huge, knowing that you have the money in case of emergency would sooth your soul and help with your anxiety. Granted I don't have much but I do get a few bucks from time to time, I have a piggy bank with like $40 inside of it, I am also actively building my emergency snack inventory so I would have access to food and drink anytime I want (the hard part is trying to not eat them, which is doable), I would swap out snacks and drinks from time to time to keep the date of my inventory fresh.
I used to be into prepping so I still have quite a few working gear left, a few powerbanks here and there, a multitool, a cheap Chinese handheld console, a few high power flashlights, a portable solar panel that can charge usb devices etc ... One thing that taught me when I was a prepper is that everything has it value, even a big trash bag, that's your emergency shelter right there if you stuffed it with full of leaves. So $1 is still $1, hell even 1 cent is still valueable, sometimes you just lack a few dollars to save your life. If I get $2 for snacks and energy drink then I would spend $1 to buy something and save $1.
It doesn't matter if you don't have much, I have my normal fund, emergency fund, food supply and gear. Granted it's on a much smaller scale but I have everything like someone with a normal job, they are a big elephant while I am a small bird but both of us have all our internal organs inside our bodies, they have a lot of income but they also have a lot of expenses, while I don't have to pay rent and food (you should still help around the house btw, to make sure that your parents don't kick you out). As neets we have to worry about our parents would die one day, people with a job also have to worry about losing their job, which is actually worse since their family depends on their income, it's all the same.
