When you know what you want and WHY you want it, your journey becomes more meaningful. When you fixate on the little flag 500 yards away it's gives you something to shoot for and it keeps you away from the hazards.
Anyone who has ever acheived anything created a clear vision of what their arrival looked and felt like. When your vision is driven by a burning desire and ignited by your passion and purpose nothing can stop you.
Without this GPS for your life chances are you will wash up where the wind takes you. Arriving at your destination is a lot easier when you know what it is and it may have already passed you by.
