What path should I take?

I want to create my own career path but I don't know where to start, I even don't know exactly what I want to become, I said I want to be business owner someday, but I don't know what kind of business I am talking about, I want to become a manager or shall I say a team leader but where and in what organization?

I don't know if I need to find an opportunity to start my career path or I think it's more of building my own opportunity to start up my career path. But as of now, I need to know what I want, what I really want to do and to become and the moment I already knew what I am up to, then I think the door leading in the career I want will open on its own.
