Great short-form profile on Neil Youngberg, a 3rd generation craftsman who owns a metal fabrication shop. Two of my favorite quotes:

I'm still learning, and I always will be. That's just how it is. That's what makes you good at what you do. You want to learn more. How to be better at it or quicker. When you don't learn, you got a problem. That's when you're through.

In retrospect, mistakes are what teach you, that's your education. So, you learn from your mistakes. At least that's my experience.
