The author, a retired scientist who has published over 100 articles and has authored, co-authored, or edited a half-dozen books, tells the would-be author how to plan, prepare, publish, promote, and reap the pay-offs from writing a book, fiction or non-fiction. PLAN: determine your goals. Why are you writing? For self-satisfaction? For family, friends, and acquaintances? For the mass market? Your choice will influence how you go about publishing: printing, self-publishing, or using an indie, subsidy, or traditional publishing house. Writing for a large audience requires thinking about demographics: who is your ideal reader? Age, gender, location, race, ethnicity, income, politics, ethnicity, marital status?all count. PREPARE: book writing tips are given, from a constellation of authors. Nonfiction, approximately the truth, requires a degree of research that fiction, not necessarily the truth, will not, although historical fiction will need to take place in a real time and place.
