Same, my favorite job was working as a (non-certified) machinist and welder that designed and made in-house jigs and equipment for a factory. I loved designing the parts and then turning a pile of stock into a useful piece of equipment. I ended up becoming a PhD scientist and still miss that job. The worse part is that I totally could have made a decent career out of welding. My cousin is making more than me as a welder without any degree.
