Portrait of me as a writer now

I am a writer who tend to include tons of vague details that mess up the story even if I don't want to. The unnecessary things just come together with the significant elements that I add to my writing. When I try to be careful about what I am writing, my pen or keyboard stops. I can't keep going if I focus on two things at the same time. So I always come back and revise a lot of things later rather than trying to start with simple details. I am also a writer who focuses on one topic while I'm writing. When there is a topic that I'm writing, I can't stop and move on to the next one. I always get stuck at some point or don't come up with any idea at all. The only solution for me is, again, to revise the piece as much as I can to change any redundancy and vagueness.
