A bold move. Remember that life isn’t necessarily about getting to “Point B” as quickly as possible, and it is wise to keep many paths open rather than take what seems to be the fastest one. It also helps to be able to explore things you never knew about and learn from others to become a well-rounded and capable person. Of course, different people’s results vary but in my opinion, high school is too early to decide that education is nothing but a hindrance.
For me, real learning didn’t even start until after high school, and I still consider the knowledge, skills, experience, and relationships from that education to be priceless, even where they didn’t directly contribute to where I am now. I never could have gotten as far on my own, and I never would have thought it would be so valuable to me. I’m not saying you’ve made the wrong choice, but don’t be so quick to dismiss the others.
More importantly, the person I thought I was and the places I wanted to go have changed so much over my life and still do. At one point or another, I thought I knew exactly where I wanted to go beyond all doubt, but new experiences can change the way you see things.
In any case, keep your mind open; you’re young. Best of luck on your journey.
