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?
