Depends on how much the business is interferring with your studies. I think education should come before business, and if my earnings were $10,000 a month I would still stay in school. I only have this year left and then I finish school, so it's no big deal.
Though I am in university, I prefer education over money. Money makes you rich, Education makes you wise.
If you were able to make $10,000/month while still being able to pay for courses and keep up with schoolwork, I would definitely stay in school. That way you would have both a great education and some money saved up.
I would definitely stay in school. I'd just be able to enjoy it more without the financial burdens. I quite enjoy school and I have a goal that I want to reach so I'm definitely not giving up.
