I don't know if it is common or not, but writing my book proposal is actually an interesting exercise. It is helping me block off the significant parts of the book. It kind of reminds me of a segment from ' Something's Got to Give'- you might remember- the movie with Diane Keaton and Jack Nicholson? In it, Keaton has been in mourning after falling head over heels for Jack- and her daughter had caught her crying about it on the beach. The daughter tells Keaton that seeing her mother this upset is why she ( the daughter) won't let herself love wildly.
Keaton looks at her and takes both of her hands in hers, and says, " You don't really believe all this stuff you talk about, do you, that you can just keep running away from love, because you might get hurt- I threw caution to the winds, and had the time of my life!" The daughter says, " I have never had the time of my life!" And, then Keaton takes her daughter's hands in hers, and brings them up to her heart- pressing tightly against her - and says, "What, what are you waiting for?"
