Then, when the book is published, send an email announcement to everyone you know.
After nearly ten years of writing regular columns for places like Time, Rosie, Lifetime, the Discovery Channel Online, the New York Times and even a now-defunct magazine called Netguide, I know a lot of people. This week I wrote to some to tell them about my book. In response, I received many nice notes ("Congratulations," "Can't wait to read about Kentucky," etc.), but of course those are not the ones on which I dwell when I lie awake at 2 a.m.
No, what sticks in my mind are ones like "...didn't know you are a writer," "Michelle: You are an spammer" and, perhaps my favorite, "I can't imagine where you got my mailing address," which came from a person who once had corresponded with me at some length about the time his car was hit by lightning. Clearly what we had shared ("Did you feel a jolt? -- M" "No, no jolt") meant more to me than to him.
