You don't have to be some kind of astronaut to afford this shit. Even if you work in some restaurant, even if it is everyday, you can still easily afford an awesome TV, latest PC and consoles.
You just have to know how to use your money.
Don't buy useless shit, think twice before you buy that desk when there's another one that's way cheaper and will even more awesome if you repaint it.
Don't spend too much if you go out. Drinking is ok but don't get shitfaced.
Forget about a girlfriend. Bottomless pit, really. Although I'm generalizing and exaggerating but girls loev money. They will also leave you less time to enjoy anime, remember the thing you started working for?
Smoke pot? Sure of course, but don't go buying more that you can or want to smoke. But don't worry, since you will be working and will no have time for that shit anyway.
Finally, food. Don't start eating in restaurants because you've got money now. You can have the best meals ever with a little bit of creativity, even if your cooking is weak.
