Chill. Not facing the realities of your own failures will fuck you over when it's over something that's actually important. If math isn't your thing and you have to take it because it's high school so you cheat, it's not going to fuck you over. Did cheating make me lazier? Yes. When I got to college and I couldn't rely on cheating to succeed whenever things got tough, I figured my shit out and ended up with a 3.2. The ability to adapt to change is definitely as valuable as perseverance.
Did cheating help me? Absolutely. It taught me that banging my head against a wall doesn't do shit. Sometimes you're just not going to get it, and it's better to find a more efficient way to achieve your end result (a good grade) than waste your time... so I schmoozed with teachers after class, learned to bullshit papers like a pro, etc. I then took that time I saved and applied it to classes that actually had an effect on my future... or I drank myself silly, but either way if you think doing poorly in a class that has no effect on your future but does have an effect on your GPA is better than cheating, you're out of your mind. Lastly, as I said, taking advantage of the system is an invaluable skill that has saved me numerous times in and out of school. Don't hate.
