We have limited attention. Our ability to prioritize this attention is one of the few things we can truly control and is one of our primary sources to gain more power from the world.
Great decision making means you can have more of what you really need. You will have all the time in the world for the most important things. Decision making is powerful: not only does it mean commitment to do something, but also decision not to do something.
Decision you make, sharpen your focus, you will get more productive. Through deciding what to do, you decide what you become!
