In every aspect of your business (and personal life) try to allow others to build their success around your own success. If you run a hotel, what can you do to permit others—airlines, luggage retailers, tour guides—to be part of your network? Rather than viewing their dependency on your success as a form of parasitism, or worse, as a rip-off, understand this tight coupling as sustenance. You want to entice others to create services centered around the customer attention you have won, or to supply add-ons to your product, or even, if it is a new-fangled idea, to create legal imitations.
