Embarrassment is a toll booth on the road to something new. Pay it and keep driving.

Nearly everything worth doing has a stretch of looking foolish attached to it, right at the start, where you are visibly bad in front of people who are not. It is a fixed cost rather than a sign you should turn back, and you cannot get past it by finding a cleverer route.

Decide in advance that you are willing to pay it. Ask the beginner question, attend the class where you are the worst, post the first attempt. The feeling is brief and the alternative is not going anywhere new.
