I would say stick with what you know. And when you're ready to grow, diversify within your knowledge realm. That's one way to keep your focus strong and still be diversified. If our retail business takes a dump, I've still got these other companies that can work with other companies. You see what I mean? So that's one way people can keep the focus. But generally speaking, most people cannot focus the way it needs to be focused on multiple businesses and be successful.
