Just take the imagists. Their heads explode.
I've been taking a voice acting class, which is still a sentence I am not entirely comfortable saying aloud. I am taking this class precisely because merely talking about "performance" is so far outside of my comfort zone and because in the fantasy version of my life I am the kind of person who occassionally contributes to video games.
Early in the first session, the course instructor gave me the note that I don't seem to be entirely comfortable being playful. So like the Professional Good Student that I am, I immediately resolved to "get better at performing playfulness". Heh.
Many of us have worked and studied for years to reach a stage in our lives and careers where our primary utility in a given space is how good we are at a thing. That can feel good, or it can feel like a trap. That can lead to coasting, and to boasting. And then we might stop trying (or being pushed) to grow.
I've written before about the practice I try to follow of letting myself be a beginner. Taking this class is very much in service of that, too.
