Hmm. I worked at factory earning almost minimum wage, while studying, for 4 years, before moving on to a proper office job.
Living w/ my parents and adopting a very strict financial regime helped me out a lot. I managed to build a decent PC, buy a car, go to anicons, travelled to Japan, etc…
I took pleasure not from instant gratification in buying that new figure, but in the commitment to, and accomplishment of, the goal I set that was to buy said figure.Save, plan ahead, don't contract debt.
I think it's doable.
Even for NEETs. If you're very emotionally unstable, try setting smaller, easier objectives, and work your way up. The hardest part is getting a job. From the shit I've seen, anyone can get a job, no matter how crappy it is. It pays and that's, not all, but, most of what matters. This mindset helped me.
