The late Stephen R. Covey was brilliant in this very simple concept of beginning with the end in mind.  Regarding this subject, he stated:

To begin with the end in mind means to start with a clear understanding of your destination.  It means to know where you’re going so that you better understand where you are now and so that the steps you take are always in the right direction.

Dr. Covey not only emphasized going in the right direction, he also taught that it takes leadership to make sure one is going in the right direction.  He taught the following about the difference between leadership and management:

Leadership is not management. 

Management is doing things right; leadership is doing the right things. 

Management is efficiency in climbing the ladder of success; leadership determines whether the ladder is leaning against the right wall. 

The leader is the one who climbs the tallest tree, surveys the entire situation, and yells, “Wrong jungle.”
