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'.
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.
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.
In quiet moments, I love to read.
