Over the past couple of years, I've had several entrepreneurs tell me that they've discovered that the place where they live and work is not their primary market for their business. Some of those entrepreneurs are dejected, and some see it as a revelation that has changed the way they grow and market their business. As an entrepreneur, you have to identify -- or come to realize -- where your land of opportunity is, and go chase it. Your time, energy and resources are valuable and limited. Use them wisely.
