Dedication:

            The dictionary defines dedication as “a devoting or setting aside for a particular purpose or; a self-sacrificing devotion.” 

When you are truly dedicated to something it becomes the primary focus of your being.  Everything you do and every choice you make is driven by your devotion to the cause.  Will the choice get me closer to the goal in which I am dedicated?  If you are truly dedicated you will make sacrifices in other aspects of your life to further your cause!
