““You don't need to be 100 percent better to see a 100 percent improvement. You just need to be a little better. There's a concept in play here called the winning edge. It means that a small change in the right place makes a huge difference in the end result. In golf, a 1-mm difference in the angle of the club head means the difference between “middle of the fairway” and “you can't find your ball.” In a horse race, the winning horse often wins “by a nose,” but that split second is usually a fourfold increase in prize money. In sales, the tiniest perceived difference between competitors can mean the difference between receiving all of the business or none.””
