When writing or creating something large, you can easily get lost in the process.
Ideas flit about and you try to keep track of them all.
You chase down dead ends. You jot notes down to remember certain things and then lose the notes. You write and realize that the last six paragraphs are a waste because you just wrote in a giant circle. You forget important ideas until the exact moment you are working on a different, essential idea and can’t stop. You switch topics and then lose track of the first, or was it second?, important idea.
And this does not take into account all the thoughts/decisions with the publishing process.
You can become really discouraged as this unfolds before you.
However, you will always be o.k. if you can answer one question: What is the next step I need to take?
The creation of any complete, complex work actually hinges on answering this one single question repeatedly.
Answer that one question, and you will be surprised how the work is capable of moving on, step by step, even if you feel lost or overwhelmed.
In an endeavor as large as publishing a book, there is really only one question to your potential success: what is your next step?
