In nautical terms, a 'Bearing' is a point on the compass marking a straight line to your objective. The term 'Mark' is a time stamp on your bearing. As things move and change, your bearing will change. You need a frequent updated 'Bearing Mark' to stay on course.
Once our journey begins, the only thing that changes is the direction we are heading. A true course heading requires constant attention. When we get off course, we can make course corrections.
In the course of your journey, you will be greatful for as many "Bearing Mark" adjustments as necessary for you to maintain a steady course.
