When we are criticized we usually take one of two approaches, either assess the information and see how we might benefit from it, or else, attack the source.
The book has been blessed by many reviewers. Two reviewers did not like it, and suggested junking what I had and starting over. On assessment, it was clear that the book they wanted was an entirely different book from the one I was writing, so I could just disregard their criticism. However , I realized that they were part of the audience and if they didn’t like it, some other people wouldn’t either. They had many useful comments as to why they didn’t like it, and while I didn’t follow the suggestion to just start over, I did incorporate many of their suggestions, and the book is much better now (trust me on that), thanks to them.
If we are struggling to cope with ADD or ADHD, we probably attract more than our fair share of criticism.
