A person who won't observe has no advantage over one who can't see. A person who won’t listen has no advantage over one who can’t ear. Good leaders use their eyes to observe and ears to listen to take advantage. The more you observe and listen, the more you can take advantage, as each time you do so, you can learn a lot. You can learn what to do or what not to do just by observing and listening to other people; you can get insight that you wouldn’t have had otherwise. This is helpful to make better decisions, to choose which direction to follow, to get a better overview, or to be more creative. As Richard Branson said: “We have two ears and one mouth, using them in proportion is not a bad idea!” We have two eyes, two ears, and one mouth, using them in proportion provides good ideas!
