As a gigging musician you can focus on the quality work calls you are getting, and how you compare to your friends.
Or you can focus on improving your craft day in, day out. On achieving a greater level of mastery, even if the gigs suck. On staying the course, even if your audience sounds like a field of crickets.
The first path (the path of ego) will drive you to distraction. The path of mastery will always lead to a positive transformation in every part of your life.
