“I fear not the man who has practiced 10,000 kicks once, but I fear the man who has practiced one kick 10,000 times.”
Another quote, usually attributed to Bruce Lee, and in typical Lee fashion, ambiguously crafted to mean everything to everyone. Figuratively, it implies that you are better off practicing a few effective techniques repetitively. Often, it is used an excuse to not investigate alternative moves. And btw, this same quote often features 1,000 as the magic number of mastery. But we will stick with the even more difficult 10,000.
If we break it down to left and right, this equals 5000 kicks per leg per year. In a 52 week year (taking two weeks off, which many of us never do), that breaks down to 100 repetitions per week. Even if you only practice martial arts 5 days per week, that would come out to 20 kicks per day. That’s not even a warmup for most martial artists and combat sports players.
So go ahead and put your year in, but please take the opportunity to open your eyes to more kicks and moves so that you can have a more diverse library to choose from. And don’t forgot, Bruce more likely practiced and/or evaluated 10,000 moves 10,000 times.
