Mastery of a craft isn't all that it's cracked up to be.
Several decades ago I decided that I wanted to learn how to do high end custom woodworking. I started with the usual small stuff and progressed to bigger stuff, often from published plans, and eventually started designing and building stuff of my own. I got really good at it. I mean really, really, really good at it. All aspects of it.
One day I looked around and realized that none of it was a challenge anymore. I could wander out to my shop, grab some wood, and start cutting and assembling nearly anything that crossed my mind. No plans required and the end result would be as perfect as human hands can make it.
It wouldn't even take hardly any time to make something that once upon a time could have taken days or weeks. There literally wasn't any challenge at all and no purpose remained.
I quit. I still have all the tools and machines but haven't touched them in 15-20 years. Mastery of any craft has its desirable qualities. One of which is to teach. But mastery for the sake of mastery and nothing else is a dead end street.
