Business ownership

I've always thought it would be cool to own our own little business, but I could never come up with a good idea for one. It seems everything is already done to death. Maybe we should just find a small business for sale one of these days. Though not right now. Hubby has a great job and I like the stability. From everything I've read running your own business is a ton of work and a big investment, so if we ever do something like that it would be years down the road.
