Write some crappy ones first.

   [not as crappy as mine]. It gets you through a lot of the
   hurdles of "THE PERFECT BOOK" by getting you UP TO the very same
   point you'd be at IF YOU HAD written the perfect book.

   Then you know what's ahead of you and the earlier parts of the
   process are no longer scary.
   For example, there's always self-publishing.

   - Ingram, while it has startup fees, has a huge distribution
   network that can go worldwide, and you can appear on bookshelves
   in real stores.

   Of course then you'd have to wear two hats: One creative writer,
   one saavy business person. Or get an agent. But I don't know
   anything about that part yet 'cause I haven't written "that book
   that will change everything for everybody" yet :P
