Pardon me if this sounds ignorant, or if my world view is limited, but I'd like to learn more about your mindset, Taco Dan. For me, due to my parents, peers, and personality, I have a hard time imagining how a person can be failing high school because they hate doing the work. I hope this doesn't come across as offensive.
I link motivation very closely with intelligence. It's true that there are individuals who seem very smart, but don't achieve such high grades in high school; however, in the end they weren't able to harness their supposed intelligence for the purposes of schooling. Sure, it may be boring, but a person's grades seems to speak volumes of a person's practicality and understanding--your GPA helps get you into university. Your GPA there will get you into a graduate school. Your GPA effectively follows you your entire life in this society. With your intelligence, push past the boredom, push past the laziness, and get good grades. High school is not hard. In my opinion, the only time a person should ever consider dropping out is if they already have a solid plan for what they want to do after dropping out (ex: Bill Gates-style).
Simply put, it is difficult for me to understand why a person could say "I'm currently failing high school, and not because I'm dumb, it's just because I hate doing the work." Is the short-term discomfort of schoolwork so great? I know I might be echoing those who tell you that "it's not that hard," but I'm also genuinely curious about your thinking and opinion on this.
