What should I major in if I want to be a small business owner?

I would like to own a small chocolate shop. Nothing too fancy, just like a small shop you'd pass around the mall. Is it hard to maintain a small business? Any tips from business owners and what do I major in? Thanks!
Update: Also, if it doesn't work out for me, what other kinds of jobs that pay good money could I get with that degree? Thanks again!
