You are. I'm talking to the people who see stuff like this, and think about dropping out. Clearly, that set doesn't include all high school kids.
"As for learning things you won't "use in real life"? I agree, it's good. But I'm sorry, some classes don't just teach you things you won't use - they just don't teach you. How much good will it do you to analyze dozens of books in essays about their arbitrary qualities, eh? Not that much."
...and when I was in high school, I said the same stuff. "Why do I have to learn about Keats?" "Why must I write structured essays about James Polk?" "What will I ever gain from knowing the rules to basketball?" "Why can't I just learn more about programming?" On and on.
But you know what? I was an idiot. Back then, I didn't have the perspective to know what was important and what was unimportant (for that matter, I'm still learning what to value). Had people let me study whatever I wanted to study in the 10th grade, I would have missed out on exposure to a lot of stuff that I find very valuable today. I would have turned out to be a very one-dimensional person.
Try not to find this advice condescending, and see it for what it is: one nerdy guy who has been there, telling you that you don't know everything, and don't have enough experience to make good judgments about what knowledge is valuable in life. In the meantime, you can learn something from every situation -- just so long as you want to learn.
