Thanks everyone for the kind words, and words of advice.
I agree with parts of what all of you have said, and my plan is similar to what most of you recommended.
I plan to continue college, taking one or two courses at a time at UCSB. It will be far cheaper to do this at UCSB than at my current school. I really love maths, and I will continue to study that. This will allow me not only to continue growing my business, but also to focus more deeply on each maths class. One of the main reasons that this business venture has been profitable is my math education. Behind every non-thrift purchase is a 500+ line spreadsheet in which I do analysis. Beyond that, maths is my passion. Take classes in this way will lower my stress, and allow me to study each topic with greater intensity.
I will finish my math degree. It may take me 8 years, but instead of finishing it lost and in debt, I will finish it with direction and a large chunk of change in the bank.
Best of luck to you, this sounds like a level-headed plan if you manage to stick to it. Being at a very competitive program can really take it out of you, stress-wise and money-wise. Been there, man. Slowing down a bit sounds like a reasonable solution if you keep course. As others have said, college isn't for everyone, but if it is for you, it is worth it. Props to you for finding your own path.
