Play fair, be prepared for others to play dirty, and don't let them drag you into the mud.
Richard BransonI was the kind of entrepreneur that never really felt I made it. When Mike Olefield's "Tubular Bells" [Virgin Records' first release] sold 8 or 10 million copies, I suppose, at age 19, I could've possibly retired on the money. Instead, I immediately pushed the boat and took that risk again.
