You managed to be a real life example of the word irony! Congratulations! Seriously though, ADD is a brain dysfunction. If you genuinely have it, self help books, awareness techniques, etc. only help so much- you need medication to progress past a certain point. You may have had hypofocus toward the book, but it could have also been hyperfocus and you could have spend possibly days mentally checked out from your body to read the thing. That's not something you can just "positive thinking" yourself through.
