My father-in-law Ray has taught me many things over the years, but watching the way he handles tipping at a restaurant might just be the most profound.

After a night at a restaurant where the service was exceptionally poor and bordering on rude, it was time to pay the bill. "Stiff him," was the chant arising from the table. Ray ignored us. He's good at that. Instead he quietly got up from the table and sought out our server and had a long conversation with him. When he was done, he returned to the table and proceeded to add no tip to the bill.

"What did you say?" we all asked as we left the establishment.

"I simply let him know that his service was well below the standard anyone would expect and described for him the things I felt were lacking from his service. Nobody learns from a "0" on the tip line. We learn from constructive criticism."

I have thick skin. When I wrote my book I had no expectation that it would solve everyone's issues and be universally praised. I told a colleague that I expected it to be disliked by as many people who liked it (insomnia patients are a tough crowd). What I did not expect was the lack of feedback on a site like this. To date, all of my one star reviews have no comments at all attached. In fact, for some, my book is the only book they have reviewed on Goodreads. Dear God, did they sign up, create a password, verify that password, and log in for the first time to simply slam my book? Kind reader, if that is so I really apologize. Read The Circle by Dave Eggers. His book is really good!

Criticism is a good thing. It makes us better. I am so appreciative of the readers who took the time to tell me what they liked about this book I have poured my soul into. If there is a reader who did not find it so useful, I'd love to know why. Don't stiff me and walk away; I promise, I can take it.
