If you have the opportunity to go to college, I wouldn't lightly dismiss that opportunity. Yes, you can learn Web Development in a reasonably short time, and even be good at it, but you would end up in a far better position (and no I'm not talking about "having a degree" turning the tide) if you complete your formal education. If you have the chance to go to college, it'd be a far wiser choice to lobby to switch your major to computer science, data science, mathematics, or any of the sciences because what you learn will be invaluable. You learn how to think about and discuss complex technical ideas. You learn communication skills that will enhance your ability to work with others for the rest of your life. You learn history, and context, and how you fit in as a citizen of the world.
Came here to say that I'm 110% supporting @P1xt on this one. I majored in Biochemistry and Psychology in college, and I've rarely used the textbook knowledge I gained in my classes. They also don't benefit me greatly when it comes to coding. But, my 4 years in college gave me emotional intelligence, maturity, critical thinking skills and the ability to teach myself things (both of which are EXTREMELY important in programming!), leadership skills, teamwork skills, the ability to speak and write and debate articulately, and the ability to be a global citizen and engage with the world.
Yes, all of these can be gained on the job--but college gives you the opportunities to make reasonable mistakes without really any serious consequences, and to explore other interests that you probably don't have the time to explore once you're in the real world.
If anything, college might be a good opportunity to get whichever degree you desire, but work as an intern for a web development company 10 or 20 hours a week on the side. Or, spend those hours instead building your own cool thing. Or, do both! You'll come out of college a more well-rounded, mature person, a degree, and lots of web development experience.
(On a related note, if you do choose to keep going on the college route, please don't just study all the time. Make friends, try things you wouldn't ordinarily try, explore outside the confines of your computer and desk!)
