There is a particular awkwardness in being competent all day and then struggling with the first ten minutes of a beginner’s class.
You cannot remember the sequence. Your hands will not do what the instructor’s hands do. Someone beside you seems to have understood immediately.
You may feel an urge to explain that you are usually quite capable.
It passes.
Or it becomes less interesting than the thing you came to learn.
Beginning again offers an unfamiliar position: you are not responsible for knowing. Someone else has prepared the session. You can ask a question, repeat an exercise, and spend time on something whose workings are still a surprise.
Choose the setting carefully. “All levels welcome” can mean different things. Ask what a beginner needs, how the class is taught, and whether any experience is assumed.
You are allowed to want good instruction.
Once there, give yourself a smaller assignment than becoming accomplished. Learn the first part. Notice whether you enjoy the activity. Decide whether you want to return.
There may be frustration. There may also be a moment when something works and you look around, pleased in a way that feels out of proportion to the achievement.
That small pleasure is easy to forget when most of your days depend on skills you already possess.
You do not have to make a new identity out of the activity. You can be someone who goes on Wednesdays, is still learning, and likes it.
