Just adding my 2 cents, I have been very fortunate to have steady work for over 30 years in engineering. I've worked for a fortune 500 company to where I am now one of six employees. I am the CAD Designer/Engineer, and I design from customer concept, to cutting material on the saw, to welding, machining and assembly and occasionaly driving truck. Now granted in ninety degree weather I prefer to sit in my air conditioned office, but it's very satisfying seeing a project take shape and you have a "hand" in making it happen. I'll never be rich, but I have enjoyed my work. It has also helped me see the other side, when you're looking at a print and saying what dummy designed this,, and your name is on the print....
