This is a piece of advice that most people disagree with, and so I am reluctant to endorse it. Knowing people's names is important, and it's useful to use them when appropriate, but inserting them into conversations where they do not belong is a known influence technique that will make other people cautious.

(While we're on the subject of recommendations I disagree with, Carnegie recommends recording people's birthdays, and sending them a note or a call. This used to be a lot more impressive before systems to automatically do that existed, and in an age of Facebook I don't think it's worth putting effort into. Those are the only two from the book that I remember thinking were unwise.)
