'There are a lot of things you can teach, but the most important ones must be learned.'

One thing that I would love that someone else had shown to me when I has in high school is what does it mean to learn, and how to learn. These are some resources that really helped me understand the value of true learning [1][2][3]

What I would recommend is that you wait some years to get into university/college. You really have no reason to rush, and the whole experience, if you later choose to live it, could be much more enjoyed if more maturity. Go travel, study programming by yourself or doing projects, study languages in other countries, take some telecommuting jobs, take some risks, and above all else, learn what does it mean to learn.
