Switching hats, changing gears, taking your meds
You have decided to publish your book yourself. Great. I'd love to help you do that. Please understand, though, that while writing a book requires all the free-flowing creativity you can muster if it's going to result in anything people will want to read, publishing is a business that requires a more disciplined creativity.
If you are going to publish your book, then you are going to be a publisher, and that means you are running a business, not an atelier. You have to take off your writer hat and put on your publisher hat.
And when you are wearing your publisher hat, I beg you, I implore you, at least until we get the product out the door, after which you can be your wild genius self once again, please take the meds your doctor prescribed.
