Funny story on welding and humility.
My most humiliating situation as a welder, ended up making me a much better welder.
What happened was, I got laid off early in my welding career, and so they kept us on, but we had to be laborers. For a welder, that is kind of humiliating. So one day we were in the bilge of this ship sucking up paint chips, and the next day we were in an engine room painting jet fuel lines. But the rest of the guys were slopping on the paint, and this was a US Naval destroyer, and I figured if I did a good job, I would not be sucking paint chips out of the bilge with a backpack shop vac. And that is just what happened, so I painted jet fuel lines for a month because I did a clean job.
But in order to get between the ceiling (called the overhead on a ship) and the top of the pipe, I used a mirror, then dabbed the spot with my brush.
Well when I went back to welding, I realized a month of painting was like practice for welding. To this day, I will start to weld a tight spot where I have to tape a mirror into the corner, and my brain will switch over, and suddenly my hands work backwards. It is far tougher than it sounds. But in mirror welding, everything is backwards...left is right, and right is left, so everything gets goofy quick. But from painting with a mirror in tight spots, I ended up being one of the welders they grabbed when there was a mirror weld to make. (On ships, there is no skip-welds, everything is 100% welded no matter where that weld is).
It was just hand-eye coordination, but without being able to paint with a mirror, I would have never been a great mirror welder.
