The process of creating and releasing a book into the wild is unlike any other experience in the world. The long process of writing the book transitions into more of a sales role once you move into the publishing stages.
Editing can be a delight–the idea of making your book into the best product it can be sounds like an obvious statement. The reality of editing can be more like a tour Dante’s levels of hell than the pleasure it should be working on your own product. It is good reason to use an editing person. The editor can be a impartial reviewer and actively work to make your product better, however your responses to the feedback can vary from powerful apocalyptic rage to sobbing grief and shades of everything in between.
You can become so attached to the beauty of your words, the idea of changing them can trigger some extreme writerly reactions! Once you have coached yourself past this stage comes the scary stage of the public gaze.
While you may absolutely back yourself, your words, your work; judgement comes in many forms and fast and swift in the digital age. The writer must brace themselves for the potential for their work to be judged poorly, harshly, unfairly and possibly critically judged against the societal expectations of the time.
As an author, you must learn to take the good and the bad, filter the useful feedback and rise above the slings and arrows of mortal men and women. The trepidation that one might feel over this possibility can actual mar the joy of the outset of your book release. Mental strength is one of the attributes that a writer does need to develop rather quickly at this point.
If you can manage to control all those crazy emotions once the book is freed, then you may be able to consider celebrating the delivery. This means a book launch, a party for your words! This is the celebration, the time that you take to enjoy and revel in the act of creation. Try to put aside thoughts of that drat editor, the amount of time and effort you have expended, and the possibility of the offencerati crowd jumping all over you and your product. Try to divorce yourself from all the flotsam of the real world and jump into that book world you created and spend some happy time there while immersed in the delight of your cosmos.
