Content creation and urge jar

I’m thinking of using the urge jar to create a habit of content creation. I create social media posts that convert to clients, but not always. I want to create a habit to master it because I’m not doing it consistently. When I sit down to write, I overthink it and edit it and struggle to come up with ideas. It feels hard. I want it to feel easier. And I have been doing this for over a year now. Still feels hard.
How could I use the model and the urge jar to support me in writing content consistently to attract clients?
