Grown-ups do a lot of complaining!
My books are just pure escapism for kids.
Try to remember that being unsuccessful in school doesn't automatically mean you'll be unsuccessful in life. Lots of people who didn't excel in school still went on to have successful lives.
Nothing prevents boredom like a good book.
Once I have the story in my head, I write it down. The illustrations usually come last.
I had a lot of reading problems growing up.
