Thinking in Public
I have 2 accounts. My personal and a sandbox. I post everything in my sandbox. It's got 2 followers, me and my mom. Thanks mom.
When it's good, I bring it over. It's not because it gets a like or more views. It's because after a few weeks of it, it resonates with me. I like it.
With two followers, one of them my mom, nobody is watching. A post that flops there costs nothing, so I post everything. The account holds the drafts. The main one holds what I still like weeks later.
Picture a chef who tries a new dish on the kitchen staff before it goes on the menu. Same idea, with posts.
Open a second account on the platform you use most. Post everything there. Wait a few weeks, then go back through it. Move over the posts you still like. How you feel about the post decides it.
Knowing what you like is a skill that builds with use. Related: Creating content is self development.
