NEETs don't work. I'm assuming you're in America, because, America, fuck yeah.
The first thing you need to do is scam yourself into some SSDI.
ssa.gov/disability/professionals/bluebook/12.00-MentalDisorders-Adult.htm - all the "mental" disorders you can get free money for life with.
"12.08 Personality disorders" are your bread and butter. If you're here, I assure you, you qualify. If you exhibit a handful of these signs, you're set for life:
A. Deeply ingrained, maladaptive patterns of behavior associated with one of the following:
1. Seclusiveness or autistic thinking; or
2. Pathologically inappropriate suspiciousness or hostility; or
3. Oddities of thought, perception, speech and behavior; or
4. Persistent disturbances of mood or affect; or
5. Pathological dependence, passivity, or aggressivity; or
6. Intense and unstable interpersonal relationships and impulsive and damaging behavior;
AND
B. Resulting in at least two of the following:
1. Marked restriction of activities of daily living; or
2. Marked difficulties in maintaining social functioning; or
3. Marked difficulties in maintaining concentration, persistence, or pace; or
4. Repeated episodes of decompensation, each of extended duration.
There's also an entire section to qualify based on substance abuse. So smoke dope, be a shut in, and be suspicious of everyone.
Congratulations, you never have to work again.
