Mind you, all of this is technically optional. I went to a well-funded high school in an affluent suburb, and there were certainly students who had schedules like yours -- I personally knew quite a lot of people whose high-school lives resembled yours -- but there were also a bunch of slackers who just didn't do anything. For as many people like you I knew, I knew just as many stoners (including two guys who were sent to the alternative school multiple times a year because they were too stupid to not get caught with weed on campus). I even knew a few people who dropped out.
I followed the middle path, taking advantage of a quirk of Texas law. You see, I have less than zero interest in athletics and little to no interest in other after-school activities. I wanted to go to college, and my dream involved getting a CS degree, but I couldn't care less about getting into some prestigious private and/or out-of-state school or what have you.
This was good because I live in Texas, and Texas law requires all state universities to accept any in-state student who graduates in the top 10% of their class. So I just made sure to do well in my classes. I participated in virtually no extracurriculars (except one club that only met sporadically because I had a personal interest in it), I took exactly one AP class because I knew I'd breeze through the material (AP CS 1; I would've taken AP CS 2, but it was cancelled my senior year due to lack of enrollment), and I only took a small handful of PreAP/Honors classes because they were in subjects I knew I was good at. My lack of extracurriculars helped me to have the energy to pay attention in class, and I took easy classes (well, easy for me). Hell, I was so good at paying attention in class that I could do virtually no studying outside of class and still ace almost all of my tests. My evenings were free as a bird. As such, I made straight As (and often A+es, which counted for GPA in my high school) in almost everything with little effort. I made the top 10% with about a dozen students between me and the cutoff, and I went to a very nice state university that's known for its CS program.
I made some incredible friends in college, who I'm close to to this day, learned a lot of things that I still use in my thirties, and those four years at a state school were the best years of my life. Whatever else I regret in my life, how I went about my schooling wasn't one of them.
Yes, I should have mentioned that I went to a modestly-funded public high school in a small dying steel town outside of Pittsburgh, Pennsylvania -- most of my classmates were the aforementioned stoners as well (they graduated to heroin -- indeed, my county has one of the highest rates for heroin abuse in the country).
For some reason, I believed that I was destined for a better life, I really loved computer programming and I wanted to live in Silicon Valley, and I worked my ass off for it. There were no handouts, and I knew I would be judged with the same yardstick as the kids from the likes of Phillips Exeter with their near-perfect SAT scores, the byproduct of personalized tutoring. The web site College Confidential was my bible. I'm one of the few that left the town, and now I live in Silicon Valley.
Still, I got thin envelopes in the mail from all but one of my reach schools. I took the opportunity I had and ran with it.
I have zero regrets as well. Turned out that playing one hour of Counter-Strike a day instead of five had a much bigger payout.
