I never watched the original Karate Kid movie. For one, it never appealed to me (I'm not much into karate or fighting movies) and for two, I was a 90s kid. That just means the 90s was my world and the only 80s thing I really cared about was my birth (lol, that statement isn't completely true but I'm just trying to make a point.)
Although I've never watched the original Karate Kid, there was one phrase I couldn't escape: "Wax on, wax off." I actually heard this often as a child, whether it was through a relative, teacher, or strangers. I never really understood what it meant until I got older.
Apparently in the movie, the main character, Daniel, asks the maintenance man if he would teach him how to fight. The man, who many know as Mr. Miyagi, agrees to train Daniel, but he starts him off doing menial chores. "Wax on. Wax off."
Daniel believes he's just a slave to Mr. Miyagi until he realizes the power of habit. He doesn't realize how those simple movements actually serve as the foundation for his training and victory to come.
