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.
Frequent "Bearing Mark" readings will help you maintain a true heading and stay on course.
