No one taught me to do anything.
My older brother gave me a car, and my younger brother was so jealous that he pulled all the plug wires off the engine and strewed them around the yard. I guess he thought he had two blocked me, but I asked a neighbor how to deal with it and he drew me a picture of the firing order. I reinstalled the wires acording to the sketch and drove away.
That's where I learned to listen. (And to fix dead cars)
