Getting Exclusive

Can you expand your business by shrinking your pool of prospects?  You bet.  If you have a particular type of customer who is more profitable, why not position your company as one who caters exclusively to that type of customer?  Fifty years ago, a laundry service had grown beyond its ability to keep up.  The owner decided to scale back, so she positioned the company as a laundry service for bachelors only.  Instead of shrinking, her business exploded – because she had made it exclusive to a class of high-volume customers.  Is there a way to apply this to your marketing?
