Do you have a system to learn from your past content?

We all check analytics, but how do you actually learn from your posts over time?

Do you just repeat what gets likes/comments?

Do you follow trends that work for others ?

Or do you have some kind of system?

For example:

Do you log anything about your posts?

What do you track (hooks, captions, CTAs, format, etc.)?

Do you use a spreadsheet, notes, Notion, or something else?

How do you review past content to decide what to try next?

Would be interesting to hear how everyone approaches this might help other creators too.
