I just have to say that both JD and I draw on a deep reservoir of physics education, for us, engineering school started way before college.
As a young kid I took apart my sibling's toys, and then attempted to reassemble them.
In my later childhood years I learned troubleshooting by taking an old radio's cover off and taking all of the tubes down to the drug store to test them -- and if that wasn't possible, simply replacing one tube at a time with a hope-it-is-good tube until the thing hopefully didn't catch fire when I turned it on.
My late teen years as well as young adult years saw me working on cars 'cause I couldn't afford to have someone repair 'em, let alone buy a new enough car where weekly major repairs weren't needed.
By my late 20's I was repairing my own computer 'cause I couldn't afford to have someone else do it. In reading the manuals, and using troubleshooting skills learned with the tubes, I usually fixed it. In 1995 it became my career.
