Nice to meet you, and welcome to the message board.
Doesn’t have to be University. It could be a lot of trial and error, but continuous education! Learn from all of the top notch people from here, start by just reading all of their post, then get books, lots of it.
Also start by doing something small, I mean really… really small. When I was in High School, I was into art, but I didn’t do art, I sold art. I started selling stuff other people wanted, like when someone wanted a tatoo idea, a logo idea, or just graffiti of their name, I sold them all.
I later went to selling artwork from up and coming artist. I also started my own online art biz, and I thought I had made it big… WRONG! I didn’t have the proper knowledge to take it further. Unfortunately for me, I had financed most of this by using credit cards that were 16% interest rates, and was only making my minimum payments, I got into a lot of debt, because I didn’t know how to manage THAT DEBT.
To answer you questions:
University: Just get educated in any form possible.
Real Estate License: Read what others have to say about this, I can’t help you on that.
Pay off my debt before business: Um, YEAH! If your living with your parents, you should get a small part time job, I would allocate a good chunk of that money into paying off the debt first, and save a little for your start up cost.
Etcetera. Keep thinking of ways to make money on the side, whether selling stuff on eBay, Craigslist, or the likes, but don’t be limited to your big goals, start small, then big.
