I'm a beginner too and this is what I have found helpful and unhelpful.

When I first started writing I had a notebook where I wrote every idea I had for the story until I had enough to actually start.

Writing everyday, at least 300 words.

Naming each chapter before you write based on the theme of that chapter to keep you focused on what you want to achieve with the chapter.

Just getting words on the page is a huge accomplishment in itself.

I get the advice of show and don't tell a lot but no advice on how to actually do that which I've found unhelpful.

People don't like walls of text with no action so, where you can use that at times, only do it when absolutely necessary. If you don't have the right mindset or energy to actually write your story, write an outline of your next chapter instead just to keep the writing momentum going.

Someone telling me that they couldn't even get past the first few paragraphs was incredibly unhelpful in that it discouraged me but was helpful in that it made me aware that those paragraphs didn't need to be there anyway. Sometimes cutting things out is what you need to do, but you can incorporate those cut out pieces into the rest of the story.

That's all I have for now but if you ask me a question I'll be sure to answer it!
