How Do YOUR Writing Shoes Fit?

The book title that caught my eye, and inspired this reflection on writing, is Ballet Shoes by Noel Streatfeild. Although the edition I have is the 75th Anniversary Edition, I just bought it and read it for the first time this summer while I was in Walton-on-Thames, England. It says a lot for a book when it is still in print so many years after being published. I wonder how many of the plethora of books published for children in 2012 will still be around in seventy-five years?
