Love Thine Enemy

It is difficult to do, but having an altruistic approach to your market will pay dividends.  Restricting your competitors or restricting your customers will almost always back fire.  We try hard at PLP to focus on opportunities that will help customers or help the market.  We operate with an abundance mentality versus a scarcity mentality.

If you work with a scarcity mentality then "if you get a bigger piece of pie then there is less for me."
If you work with an abundance mentality then "there is more than enough pie for everyone."

Tom Peters, management guru, has an excellent blog post on this.
