This may sound like a ruse, but I really believe it. And it is phrased in a way that doesn’t even make sense, so that’s how you can be sure it’s authentic:
Writing with joy
If you have (or find) joy, you’re golden. If you don’t, nothing is going to go as well as it could.
Can you write your way into joy? Sure.
But we might also ask: What would I write about that would bring me joy? And how might I write that would be the most enjoyable?
