Erosion
I heard a reference yesterday that is sticking with me. It was that erosion was the big threat to a rock. Think, the Colorado River and the Grand Canyon. Subtle. What happens when erosion happens to the values a person holds dear, or to guiding values? Does one lose something important? Does one become desensitized? Uncaring? Frightened? Brazen? This conversation can go in multiple directions.
It would be a healthy exercise to recall decision points in life where things went well, or went poorly, and to look at what triggered a good decision or a bad decision, and then follow the thread.
