1. Don’t hold back on that fantasy site visit / phone call / interview / query / meeting that you have always wanted to do, lest it become too late to include the results in your book. Do it now! This book is your golden ticket.
2. Don’t lose track of your notes and/or future ideas for inclusion by writing things down in multiple notebooks or on scattered pages of the same notebook; concentrate, aggregate, cohere, reread, and compress. Keep it all in one place (with back-ups). Obsessive-compulsive organizational habits are your bestfriend; telling insane and vaguely embarrassing stories later on, about how you used eight different colored markers, four highlighter types, and multiple versions of extra pages stapled into a vast mega-notebook that you re-read every night before bed – and that you also took digital photos of lest you lose the whole thing in a house fire – will be a lot more fun than explaining how you forgot to include certain things and your book sucked because you never got your shit together.
3. Quick, tossed off, last minute additions, typed right before you submit the final manuscript, probably aren’t a good idea, no matter how funny or emotionally powerful you might feel they are at the time of impulsively writing them. Always allow time to come back and read something from a distance.
4. And run all quirky one-liners that you hope to include in your author’s bio (do you “always enjoy a good latté”?) past a close friend; they don’t age well.
