"PATHS AND GOALS Series of goals. 3. Since you do not want to keep changing direction while you walk and do not want to spend your whole time re-calculating your best direction of travel, you arrange your walking process in such a way that you pick a temporary "goal"--some clearly visible landmark--which is more or less in the direction you want to take and then walk in a straight line toward it for a hundred yards, then, as you get close, pick anothernew goal, once more a hundred yards further on, and walk toward it....You do this so that in between, you can talk, think, daydream, smell the spring, without having to think about your direction of walking every minute.
