When I was a kid, I watched the movie Karate Kid where young Daniel wants to learn Karate and gets old Karate master mr Miyagi to train him. Miyagi lets Daniel clean and polish his cars using the “wax on, wax off” motion. He also lets him clean a terrace and pain a fence, always using special motions with his hands when appying the wax, paint or cleaning water. All in all, Daniel spends lots and lots of time with these activities until he finally snaps and goes furious – “When are you going to teach me Karate?!” It turns out, that is precisely what he has done. The special movements Daniel used in the activities are important Karate moves, and by doing restoration and renovation work, they have just killed two birds with one stone. A lot of works has been done, and Daniel now has the correct movements in his muscle memory.
