I always feel that the word writer is too big for me, but I would say that I am one (or at least I try to be one😹). I write a little bit of everything... In my case, at the beginning, I do very well writing what comes to mind, and when I have more material I try to make an outline/summary of where I want the story to go. If I'm writing poetry, I write directly what comes to my mind without thinking much about it. I encourage you to start writing whatever it is, many times it just comes out without thinking much about it or having it planned.😊
