I'm in second year and looking for something similar. I'm taking a math degree-- which, as a note, is not something I was "good at" in high school. Math is one of those things you have to change your brain around for but that in itself is not as hard as it seems (you do it every day), and it's also very worth it! Math is creative, inherently, and it will help you solve problems in general, as well as give you a good grasp of symbology (by that I mean you will be better-suited to recognizing when things are representative of other things-- very useful in any kind of analysis which you will surely need to navigate the world).

And on that same note, please try to overcome your deepest academic fears now while you're still young. It sounds like you highly value freedom, and overcoming fears will give you that freedom. I did not want to be a math major in high school, but here I am. I realized it was holding me back from what I was really good at-- which is creative analysis. Because I have a deeper understanding of mathematics, an entire scientific world has opened up to me. I now have access to in-depth research using statistical models, I can now read a physics textbook without skipping math-heavy parts. I am more free than I was without it.

If you don't think you can take an engineering or computer science degree because you're bad at math, yet you're interested in web development and graphic design, you are closing yourself off. Go for it. You will have a hard time but you will learn and grow-- can't do either without tough times.

As far as staying out of the corporate world, you may find that your opinions change. It depends on your work environment. BUT my plan is to become a tutor for some time (pays $25-40 an hour with a professional tutoring company) which will take up ~15-30 hours a week for me. You can look into that. If you like software stuff, there is demand growing for mentorship for kids in programming. While tutoring I will be working on increasing my development portfolio, and am currently toying with perhaps becoming an ethical hacker-- tutoring will give me lots of time to practice, some income to supplement, and especially time to figure it all out.

Let your career develop naturally. The difference between you and Joe-blow is initiative. Do stuff that excites you at home. Set aside a couple hours a day to just.. look into everything. Try and learn principles of graphic design on your own time, start your own projects. Read a lot. Do whatever gets your blood-pumping and makes you feel fulfilled. Don't pressure yourself, just take it slow and explore your own passions. Then, when the door of opportunity opens, walk through. You will create that door as long as you take initiative, and the opportunity will NEVER be perfect but it will be a step along your path.
