> comes from a combination of the West's allure to Eastern martial arts and the reality of plateauing during training. Once you've been doing something for 2 years, you are no longer seeing the massive learning gains you saw as a true novice.
Which is ironic given the context - Wing Chun is basically useless the first two years and’s you plateau until it finally clicks - only then do you start to see massive gains each lesson!
(why? For a long time you just go through the motions with drills, but until you >really< understand how your structure is connected to your stance (which can be over a year), your punches and movement are way off from optimal from a Wing Chun perspective).
