Correct! Each person has their own writing style and that will help attract readers. I notice this when I'm reading books. Some will really make you read more of their works because of their style.

Re-reading won't really take a lot of time. Unless you're composing a novel. 😅
So it's better to read it again and check for mistakes, or maybe improve some sentences.
I remembered when I was a student, the teacher will always say review your work before passing it.
