The most important advice I can offer is that writing is a craft that you can learn by practicing. If you keep writing, you will improve.
I had learning problems when I was in elementary school, and didn't really start to read well until high school. I never read any of the middle grade classics that were popular when I was young - 'Harriet the Spy', 'Charlotte's Web', 'The Witch of Blackbird Pond', 'Charlie and the Chocolate Factory'.
In quiet moments, I love to read.
Many writers are afraid of writing something bad, so they don't try or give up when their efforts don't lead to a masterpiece right away. If you work at it, you will improve.
