I'm not sure about what kind of business would be appropriate here? Would I be able to learn ways of earning money by opening a business both online and let's say opening a store?

I'm really interested in book sales but I don't want to own a store but was thinking about selling online. Possibly opening a website or maybe a store on Ebay which I really don't want to do.

I think I'm a tad confused now but I need to learn about so many things and I think this site is the best place for me.
