One of the more difficult adjustments for newly published authors to make -- and for established authors, too! -- is the need to work on multiple projects at once. There's the book you're promoting, the book you're editing/proofreading, the book you're drafting, the book you're hoping to sell, and . . . sometimes more! (For me, there's also the book I'm co-writing!) And if you're published with multiple houses across multiple genres, it can get really tricky to switch gears.
