Hi, the only suggestion I can give you is: stick with it. You don't need a degree to be succesfull but you do need the business ethic (ideas, insight, brains, experience etc) and to be realistic.
If you want to run businesses that's fine, great stuff: go for it. Thing is that businesses don't sprout out of the ground, they need some planning and some financials to start off with (or time). Build something first, even if its a trial product or trial website. After some testing start spreading the word, marketing and above all: networking. See what happens in the real world.
The disadvantage of the drop out thing is that people wonder if you can finish what you started, they wonder about your reliability: will he do what he says? Will he carry through? Can we rely on him? Things like that. Know your stuff. Networking is great: get to know people who own businesses and who learned through trail and error. Work for one for a while to see what it's like. It's not Cloud 9 but it can definitely be heaps of fun. I don't like the boring tax figures either (accountant hurrah) but it's part of it. Know how to add numbers eventhough you don't like it much.
About myself: A bachelor artdegree is cool but if you want to go in business it means squat. Really. I build my work exprience up by starting parttime somewhere and growing from there which paid off (4 jobs in 5 years). Every experience builds knowledge for future growth. The plan is to acquire knowledge and to follow your goals eventhough they might not be 100% in tune with where you'd like to end up. The uni degree means tiddly nada if you haven't a clue how things work in real life. Get experience and grow. Work hard. If you fall on your face, fine, that's how you learn. Get up, dust off and keep on truckin'.
Good luck!
