One activity I do indulge in, however, is thinking about and searching for the perfect word, not only for the book I am currently working on, but for passwords, user names, puns, snippets of email exchanges, and so on.
One of the best I have come up with in the last year or so is "Palabramor" as my twitter name. In case you don't speak Spanish, that combines "palabra" or "word" and "amor" or "love." Cute, huh? Too bad only Spanish speakers will recognize my wit.
In this vein, I have been playing with the idea of a business name for quite some time that would incorporate all the writing services I offer, not just the memoir ghostwriting. Any writer will recognize the amusement value of such an enterprise. What fun it is to play with words. I suspect that most will also soon realize, after a Google search or two, how difficult it is to come up with something really original.
