Audition for the play. The worst version is a no. The best version is you finding out you love a stage.

The worst outcome of trying is a no, and that is a much smaller object than the one imagination builds beforehand. On the other side is the possibility of finding something you did not know you would love, which is not available to anyone who stays in the audience. The asymmetry is not close.

Sign up for the thing you keep watching other people do. Prepare enough to take it seriously and then let the result be out of your hands. You are buying information about yourself either way.
