Can You Build a Business From Passion?

Airsoft is a wall gaming sport, a bit like Paintball. We all dress up in camo, we have toy guns that shoot six and a week. And basically we're around abandoned warehouses and woods. Kelly shot Ellen in the neck. But it was a fun day. It's such a laugh. I really enjoy it. Can you build a business based out of your passion? Have you seen it happen? Have you done it? Have you experienced it? "Yes, you can build a business from somebody passionate about because I've done it"
