Etiquette, Etiquette, Etiquette! That was drilled into me when Uncle Aaron introduced me to golf. Your appearancee, club rules, rules of the game, your responsibility to keep the club as good or better than you found it etc.
I started by hitting balls in a field, then pitch in putt, then an executive course before a championship course. And even then it was clear that "pace of play" "fixing ball marks and divots" was something every player could improve upon.
