I'm sooooo confused

My Book Launch is today. What do I do? Do I lecture like I did when I was teaching college? Do I sit behind a table, pen in hand and look like I'm selling kitchen knives on Television?

One of my advisors, with whom I am related, tells me to read a chapter aloud. Another advisor, with whom I am related, tells me to relax and talk a bit about the book.

In the book I talk about the foundation of American ethics. When I discuss the Judeo-Christian roots will I alienate my progressive friends and relatives?

'splain something to me - I stood in front of classes for 30 years or so. More than once I lectured on a topic, struggling to keep a chapter ahead of the class. I wrote this darn book. I SHOULD know the material. Why am I nervous?

Well, wish me luck. I'll let you know how is goes!
