When speaking to a very small group of people you should be ableto include an extremely large amount of customization. You shouldhave researched the group and done your normal homework includingphone interviews with the expected attendees (if it is a publicevent and you don't know who is coming, be set up way early soyou can greet and interview people as they arrive.) Jot down anote of why each person attended. Then, when a section of yourtalk applies to them, point it out and name them by name.
Example: "John, you told me you wanted to learn how to sell moreto the people that visit your website. This section specificallyaddresses that, especially the part about the psychology of thesale."
Don't assume that people will perk up when you come to the partthat specifically applies to them. Make a big deal to point itout to them. You will be adding an extreme amount of value whichmakes them realize that it was a good thing they attended. Oh anddon't forget they'll love you for it.
