"she will think it is the book and not you making the changes."
When you are changing as a person, it will not be natural for a while... Your W will be confused because this is not the Shaves she knows. My W would always say things like "your just doing what those people tell you to do" and "that's what you read out of a book" It doesn't sound authentic originally. This is where consistency comes into play. You do have to be very aware of your words and actions. You have to fake it till you make it.
