Richard Koch's The Star Principle: the Business of Winning
If you are founding a business, look for a gap in the market where you will be number one from the beginning. And look for a niche big enough that you can sustain rapid growth for many years. Once you establish a leadership position, do everything you can to retain it. More importantly, if you fail to get a leadership position, or you find your niche is not as big as you thought, it is better to cut your losses and direct your efforts elsewhere.
