There is more information in the world than you can ever take in. This means that you have to select what you need to pay attention to as well as what you need to ignore. Focus means concentrating on some signals at the expense of others. Nowadays it’s not about finding the signal in the noise. The fact is that to win you have to find the signal within the signal. You must decide what matters the most. There is no right answer, it depends. Once you make a choice, then you need to share it with the people that matter the most. Finally, you need to take action right now. This means that you need a model of the world that keeps you focused on what matters most. Focus is the filter that makes a real difference.
