Ironicly, its gone the other way for me. I was working on cars long before I got into guns, and went to work in a plant shortly after I got into guns, so a lot of stuff was already second nature before I really got into shooting.
If it seems too loud, it is, and the simplest tasks are rather challenging when you cant see. Eyes and ears need protection.
If you drop a tool, let it fall!
You are responsible for your safety. Safeties, and machine guards, can and have failed in the past, dont rely on them.
Always have an escape plan.
If something seems wrong and/or you think you should be somewhere else, there probably is, and you should be somewhere else.
You forget about temporary repairs, until they fail. If you cant fix it right, let it sit broken.
If its worth doing, its worth overdoing but don't overdo it too much.
