Made to stick

I have struggled over the past few months with reading. I have started a few books but have not had the dedication or determination to finish them. One of the books that I started reading and have recently picked back up is "Made to stick" by dan heath. This book was not written with pastors specifically in mind but there is a lot of information that could really be of help.
The basic premise of the book is what message are you getting out? Whether someone is a teacher,salesman, pastor, or whatever we all have a message that we are trying to get out. The question is is our message getting to our audience? Is our message delivered in such a way that people are desiring to learn more about what we say? Is our message said in such a way that people are digging for themselves even more than what we are giving them?
Unfortunately I have been in so many church services that do not have a plan or a specific theme for the day. It may have an overarching theme of God or God's love but not something that we could summerize in a sentence. In Bible school as a kid I always remember that their was one specific Bible verse and every thing about that day focused on the lesson that the Bible verse taught. It was focused on teaching one principle. Unfortunately we have listened and possibly preached sermons that afterwards we have may left scratching our heads about was the point of that. As the great line from Billy Madison said "Mr. Madison, what you've just said is one of the most insanely idiotic things I've ever heard. At no point in your rambling, incoherent response was there anything that could even be considered a rational thought. Everyone in this room is now dumber for having listened to it." Is this what more people are thinking when they leave a service ? I highly value pastors and I think that the message we have is so important and I think sometimes we don't realize the importance of how we say it is.
