I know they are pretty direct with how they talk to you in Job Corps. So, I will be too.
The problem with school is that some of what you learn will be important later in life, and some won't - but, you have no way of knowing which is which. And even if you did know, it really wouldn't matter, because you have to get through ALL of it to successfully make it to the next stage of your career. So, it's a hurdle. An obstacle. Or a Tool. Yes. A tool. Some of what you learn in HS might make college or trade school a little easier. You just gotta keep your eye on the prize. Remind yourself why you are doing it. Kind of like having to eat your vegetables before you can have dessert!
There are things you learn that you don't even realize you remember, until one day, at the age of 45, you see that pretty little snake, but your brain starts in on that little rhyme you learned when you were 8 years old. . . "red on yellow, kill a fellow . . . " and you know what you need to do. (this happened to me!)
It's really the social aspect that often makes school untolerable. If that is the case, rest assured, all the "in-crowd" stuff isn't nearly as important later in life.
Protective Services is an interesting career. I was in law enforcement. Something different every day. Different people every day. I loved it!
Best of luck to you!
