Start A Business?

As a business student, I've been jotting down few points on how to start a new venture. Sooner or later, I'd love to be my own boss. I want to be an entrepreneur, come the time that I have the capital and right ideas.
I've been looking at different industries as of now. I've been wanting the travel, clothing, and printing industries. However, I still have to take down a few notes on which really would make me happy. If I choose printing industry, it would be helpful if I use workflow software solutions to implement my business a lot better.

How about you? Do you currently run a business? Or would you want to run a business venture? If so, which industry would you most likely be inclined in?
