Cool list! The problem with word processors like Microsoft Word is that, though they have hundreds of features, they’re not built for writing books; they’re built for writing anything and everything. So when it comes to formatting or typesetting, it’s a pain.
I also recommend taking a look at our Reedsy Book Editor, since it combines a simple, Medium-like writing interface with powerful formatting and typesetting, allowing you to export a flawless ePub and a print-ready PDF for free: https:///write-a-book
I agree wholeheartedly with the idea that you must study a variety of fields to promote creativity. Another reason that this strategy is important for a writer is this: Before you can write content for a client, you must learn everything there is to know about his business. You must know his field almost better than he does. Then, and only then, can you write about it in a convincing manner. Humor and warmth are also important elements of rich, engaging content. How can you be humorous or warm about a subject that you know only a surface amount of?
When you have a concise, creative brief that has approval from all parties, it's time to brief the creative team. Please, do it in person (or via phone/video conference if a live meeting isn't possible). Don't get lazy and send an email, or worse, leave a photocopy on the desk with "any questions, gimme a call" scrawled on it. This is not only your opportunity to start the project right, it also gives the creatives a chance to ask questions, clear up any possible gray areas, and feel you out on other issues that may come up. If you want to get the best work, in a timely fashion, be there to brief the teams.
