I never denied that it's my fault that I didn't get into college this year, I missed it, it's my fault. I don't see where you saw that "not my fault" part here.
You implied that it wasn't your fault because 1) they changed the date, and 2) you don't double check dates because you're an INTP. Don't make me quote you 
Which pretty much make the analogy void.
Then why did you make it? 
Do I have to have done something to know something? Obviously collecting facts through observation isn't enough for some reason... Oh well, thought it was enough.
The validity of collecting facts depends on one's perspective. Are you saying that the perspective of someone working a certain job is the same as that of someone who's never been in their position?
Okay, here's my definition of fair work: you do what is in your contract and you don't spend 3 extra hours in the office. What if you enjoy what you do? What if you enjoy it so much that you actually stay overnight in your office 3 nights a week (especially if you have a mini-fridge, unlimited free coffee, free electricity and wifi, a pillow, and a public restroom all to yourself)?
^Seriously? If you don't agree, at least give me a reason.
The rest of my response was a reason. A whole bunch of em'.That is too much time to think.
Bullshit. That just means you don't have something worthwhile to think about, which again harkens back to that "worthwhile cause" thing.
I prefer doing something I enjoy AND think. Nonetheless, I don't know about where you've worked, around here cashiers have to smile and be nice to the customers
You can fake it, especially if you're focused on getting them out of there (everyone likes a fast cashier), and especially if you perceive them to be non-threatening.
and by being nice I mean answer idiotic questions about the rip-off promotions and shit like that.
I had to know what was on sale in 3 different departments every week. Memorize and forget it. Plus because most employees (and managers) are idiots, sales have a definite predictable pattern to them, especially seasonal merchandise. Some things are actually literally always on sale.
That's not exactly thinking (<-which is why it's so damn easy), and waiting in line, about 1 out of 2 or 3 customers do have these questions. The rate is a lot lower than that. Perspective. If you don't do it, you get fired. You were expecting a birthday cake?
That is one of the things I've been talking about - pretentiousness. Pretentiousness can be useful if you do have something to look forward too anytime soon, but a cashier has no perspectives (<- You mean prospects), meaning no advancement.
It's not pretentiousness, it's perspective. Being able to "pretend" shows that you have sufficient perspective, meaning you have some understanding of the role you're in as well as that of a specific individual. And a cashier absolutely has prospects, they're just not necessarily within the same company.
Getting a line in your resume is not useful experience, it is a useful THING. However, I don't think that a line saying that you was a clerk is useful when applying to something that requires work experience in IT section, therefore I see that line as pointless.
It's up to you to sell yourself and tailor the phrasing of your job duties and responsibilities so that they suit the job you're applying for. Debate and writing help this tremendously. At the very least it shows you're capable of the basics, i.e. showing up on time, submitting to a dress code, interacting with customers and fellow employees, etc.
I also wouldn't socialize with the other employees (oh, but they'll socialize with you, and you won't be able to get around it), first of all - no time to do it, only after work (Bullshit. It happens all the time. Stocking shelves, meetings, breaks, lunch, when you use the business for legitimate reasons, e.g. shopping, etc), which is when I'd be heading home to spend some time alone and away from the place i hate. I'd have had enough socialization with various assholes throughout the day already... You'll get over it, and your fellow employees will probably help you through it. The first customer I checked out got pissed and smashed a watermelon in the middle of the checkout line. Shit happens.
As for masking emotions - I've learned that at home and enhanced it during the 12 years I've spend in school. Whatever you think you've learned, it'll be put to the test and improved upon. You don't exactly deal with a wide range of customers at home and at school, and both of those places suspiciously lack phenomena such as Black Friday.
As for how the store works - first of all, I have zero interest in that (but you'll learn about it anyway and apply it to other things), secondly, I believe I already know the big picture (<-LMFAO)...
The last part sounds rather pleasing, but only to some extend. First, I don't really see a good reason to manipulate the prices (by manipulating my bosses), it would be fun just for the sake of it for the first two or three times, that's it. Afterwards, it becomes repetitive, and since it doesn't give me any advantages, it's pointless too. Combine boring and pointless, and you get the ultimate "won't do" mix.
Once you're fully integrated into "the system", I'm willing to bet you'll have plenty of reasons for sabotage. Otherwise it's an extremely useful tool to shut up complainers and make your life easier, not to mention you can take advantage yourself in multitude ways. 
Not necessarily. I still might get successful with something on the internet (If it's on the internet, it must be true! Just like those 3AM infomercials!), and I might get lucky somewhere in the hundreds of job applications. As unlikely as it might be, it is possible. And that is a better alternative to hating most of your day and waiting for the same to happen, except being in a shittier mood.
Are you happy now? Would you prefer being in a shitty mood with money (a job) or without it (at home)?
For what's it worth, I'm using the net and walking around, our family doesn't have a car.
You can apply to most retail chains online as well. And uh... bus... or bicycle.
If being serious, the best outcome is having my own company related to game development. Although, I wouldn't mind a company related to technology or software instead of games, that sounds relatively good as well.
If being less ambitious, a manager's position, or analytical stuff in a firm that specializes in technology that I'm interested in would be not bad either.
As for the entry-level job, I'm looking anything tha's related to technology - server administration, computer maintenance... The latter would be the perfect hit.
Given where you're applying, I can tell you immediately that you're competing with a lot of other applicants with more experience and training, and they probably have transportation as well. You should take any job, and then keep applying and trading up. Something is better than nothing. You'll also stand a better chance of getting a tech job
Game designer works. How about you start by learning some code. Actually, you might be interested in NetLogo (based on javascript), a modeling platform that can be used for everything from modeling complex dynamic systems to creating games. The graphics certainly aren't mindblowing, but it's the shit and it has applications for nearly every field of study, as evidenced by the suite of free example models in the model library. And then if you learn advanced statistical techniques (integrated multivariate/spatial stats) on top of that, by god you're unstoppable.
