Sign up for the class where you know nobody. Fresh rooms give you a fresh version of yourself.

Signing up where nobody knows you removes the version of yourself everyone already agreed on. In a familiar group your role is settled: the quiet one, the funny one, the one who is bad at this. A new room carries none of that, so you find out which parts you actually chose.

Take one class, club or team this term where you know no one. Say very little about your history for the first few weeks. Notice what you do differently when nobody in the room expects anything in particular.
