I was thinking about just writing up rough, less detailed stories and keep filling it up with details once the story itself is "already written", working my way up kind of layer by layer instead of trying to write up things chronologically, but i thought it would be worth asking for advice from more experienced writers over here.
Lots of good advice upstream in this thread for you. At some level I think you have to enjoy writing to do it consistently and well, but that can take many forms.
Anyways, your last idea is an interesting one. There are many different ways to outline or write a book. There is one chap who starts out writing a 20 page outline and then he beefs it up and it turns into a 100 page outline and he effectively just keeps filling and beefing up his outline until he has the book finished. His name is Jeffery Deaver and you can't argue with his results.
