You sound like a smart guy so the answer is clear.
Go to college and get an accounting degree. That's what I did. Bang as much college tail as you can while you are there. That's what I did. Take what you learn from the business courses and tail-banging and apply to your business. Yes, that's what I did.
The smart people are the ones that need to go to college. Smart people go to college, get a useful degree & then apply it to their lives when they get out in a way that keeps their options open.
You are only 21 once. Don't worry, the money making investment opportunities will always be there. Go to college while you still can. I am so glad I did.
