I think this is a fair assessment. I would say that any post-high school training could be approached this way, and that is what I wish more people were open to. I think society needs to rid itself of the "Oh, you're a trucker? You must have been too dumb for college." type of stigma. My father-in-law had a master's degree in electrical engineering and held contracts with NASA for his optical systems, but he went out and got a CDL and drove trucks for a while because he had always wanted to. I often wonder what people in gas stations thought of him when he was on a trips, no way did they know that he was an expert in holography, or lidar, or that he had developed the optical disk used in IBM's first barcode scanner. Einstein was a patent clerk, kind of unassuming.
