Learning a martial art is very hard work.
It entails considerable diligence, personal responsibility, time, money, effort.
So, there is no surprise.
Very few people become skilled with any martial art.
Most people paddle in the shallow end of the syllabus, utterly unaware of the depths of the art.
They lack the level of self-discipline, faith, tenacity and commitment necessary.
The student quits before they have even started.
This is no surprise. It is normal, average, and to be expected.
