The Coast Guard's Electrician's Mate training program taught electron-flow theory, so it was tough to switch my brain to hole-flow theory when I went to college. Technically the math is the same but man it threw me off with schematics.

Was that in the context of vacuum tubes? There, electron flow definitely makes sense.
