- Repetition is mandatory for mastering a skill. It is impossible to "own" a skill in a day-long class. Even in a multi-day class, you learn the skill and get some practice, but really mastering it takes repeating it over and over, ideally with an instructor present to ensure you are performing it correctly and not creating bad habits.
- No two classes are the same. Every instructor is different. And every class is different. Each instructor brings their own personality and manner of communicating to a class. Sometimes one instructor may communicate the same idea in a different way that "clicks" with a student. Even taking the same class with the same instructor can vary from time to time depending on the other students in the class.
So yes, push yourself to take the class is out of your comfort zone, but never, ever be reluctant to repeat any class again, and again, and again. Its how you learn.
