When my father started training me as an electrician summers in 1960 when I was 12 it also taught me the basics of being a programmer

 Why?

To stay alive as an electrician working often with things hot (where you cannot turn the electricity off) because a home or business needs those circuits on, staying alive is a real problem because getting shocked (at least by 110 volts) is something that happens many times a day so you have to sort of take this in stride. However, if you are working up on a ladder you have to shut the power off because if you get hit by 110 volts or 220 volts it could throw you off the ladder and that could kill you if you are high up on the ladder enough. So, working hot only really works (if you want to stay alive) if you are on the ground already with no dangerous objects to fall on if you get shocked and your body jumps from the shock.

The point being the methodical nature of staying alive as an electrician as a young man also helped me be methodical at succeeding at being a computer programmer and computer operator too in the 1960s and early 1970s.
