And Perfection Practice makes sense.
When learning anything, repetition is a fact of life. This is especially true for karate. Unfortunately, in our computer oriented world, it's becoming a lost art.
People, particularily kids, find repetition boring. And that's where Perfection Practice comes in because this method is neither mindless nor without purpose.
Instead, each set is unique and another concrete step toward greater ability. Looking at practice this way isn't boring - until it is. Boring, you see, is the mental signal that you're moving on to the next stage referred to as 'muscle memory'. Something every master craftsman from carpenters, to jet pilots, to surgeons relies upon.
Perfection Practice is an invaluable learning skill. For kids, however, it initially requires a lot of support from both their instructors and those they want even more to please - their parents.
The bottom line is, learn it now or wish you had when you get to law school!
