I like to engage in what I like to call thought experiments. So why is something the way it is? And what happens if one key element changes? Does the thing fall apart? Or can it become something new and different? Or even better?
If you don't spend time planning, you'll spend it writing. And if you don't spend time writing, you'll spend it editing. If you don't spend time editing, then packaging becomes enormous and takes longer. If you don't work on packaging and spend time on it, then querying will take longer, because you'll be faced with more rejections. And finally, if you don't spend time querying, and just take what you can get (and that includes self-publishing—no slam on it, but it is something we do without spending any time on querying), then you will spend that time on marketing.
You can also work some magic in person. Show up to any signings or discussions, even if you just drink coffee and don't participate. Ask for the book at your local library or bookstore. Read the paper version in public (train stations are really great for that sort of thing). And you can also talk to your friends, or email them about the work.
