Thinking about business

My husband keeps telling me about his plan to have a business but I am not really into having a business. I never say no but I never say yes because in my mind what happens if he gets lucky with his business. A lot of businesses that started out small then they grow big. My husband is thinking about opening a pizza restaurant just think but who knows he might win the lottery someday. His is always in search of the best franchise to own for his business. I have no idea all I have to do is listen to him I know how he really wants to have a business but for me is not easy to own a business especially if you do not have the money to spend for it.
