There was definitely something missing from his life. Miles intended to live his life with integrity. He did not lack for vision. He could see himself involved in music, but could only see that truth based on what had already come before. Just because something is established, doesn't mean that it is the only way it can be done.
Creativity is evolution, and evolution lies in the future to be created.
This is a common belief. Yet if Miles were to take actions consistent with his fundamental being, not only would he maintain his integrity, he also would create an existence for himself where nothing existed before and he would attract those people required for the fulfillment of his vision so that he would not have to go it alone. . We tend to idealize things we want to make happen in life. We tend to compare ourselves against some external standard to which everyone must measure. We also put our trust in beliefs that are designed to hold some universal truth.
