I have carefully avoided ever being paid for anything.

That is great. And I salute you, sir. Unfortunately, I need to eat and to have roof over my head when I am sleeping and because of that wage is needed very much.

I phrased that somewhat carelessly. I avoid being paid for anything related to my hobbies as I want to keep them as hobbies.
I have a day job, unrelated to CNC or programming.
