Have you noticed? We spend almost our entire adult lives doing things we’re good at. Anything we do that we’re bad at, we either stop doing or we get good at it. So all roads lead us away from the experience of being a beginner. For me, it had been too long. And I’d accidentally forgotten how to do it.
So I took up dancing (which I’m bad at). That was really terrifying. And trampolining. And more recently improv. At the moment I’m learning to draw - which I spent most of my life wanting to do. But I never stuck with it because I hate drawing badly. But that’s just what it feels like to be a beginner. The trick is letting that go, because it doesn’t matter. You don’t get to be good at anything without first being bad at it. And being comfortably, visibly bad at something gives everyone else permission to play.
