I've been trying to write several articles that have been rejected every time. I'm giving it another go but I'm now on my third iteration of a new article and it's been a frustrating experience. Can you help me understand what I should do differently?

I'm frustrated because I want to contribute, but I feel like running into a wall. The comments left by the reviewers are well meaning, I'm sure, but it's demotivating that I have to keep revising something without knowing why. Before I give up, I wanted to consult the community. Could you let me know if there is a better place to ask my question?

Here's my question: What quality of standards should a new article adhere to? I identified a topic that I'm an expert on and would like to put up a minimal version, just do that it at least exists. The article is brief but I ensured that it's correct and that I'm citing a lot of external resources. One of the items of feedback I got was to write a "careful introduction". What does that mean? How is this brief verdion different from articles that are way more sparse and poorly written? I don't understand why it's necessary to do everything perfectly on the first go.

What confuses me is that I've tried to write responses to the rejections, but it feels like I'm talking to a chat bot. I wish they could give me examples or be concrete about what should go or what should be added.

Thanks!
