Beneficial work involving creating new things?
I’m very interested in finding some sort of vocation that gives me creative access to a machine/wood shop of some kind. I am most happy when I am solving real world problems by imagining up a solution and then creating a prototype. What sort of work would maximize this contentment and still be beneficial to humanity? Even if you had suggestions for how to do this outside of a career, that would also be beneficial.
