The danger is that a perfectionist never finishes anything. Seeing good work as Not-Quite-Ready is a curse.
When I was working as an advertising copywriter, I was notorious for not "releasing" an ad until the last possible moment. Fortunately, someone older and wiser taught me a valuable lesson: sometimes "good enough" really is good enough, and I learned to let go.
Now, as the owner of a small publishing company, I have to be a businessman as well as an artist. I realize that no money will come in if I don't approve a proof and let a book start selling.
However, I seldom stop editing. I even re-do old blog entries (including this one).
The New Yorker magazine has an excellent article about Steve Jobs, which says that his real genius was tweaking -- not inventing. You can read it for free online.
I'm a tweaker, too, but being a tweaker can be dangerous because nothing is ever really finished. (When I was in college, I was still building bookshelves a week before I was due to move out of my apartment.)
Printing on demand and ebooks make it easy to keep tweaking. Maybe too easy.
With POD and e I can make improvements to my books whenever I want to.
Unfortunately, sometimes when I should be working on new books, I instead work on old ones.
Most of my books go through hundreds of revisions but the first one to be published is good enough to not embarrass me. A person who buys version 2.13 gets a better book than the person who bought 1.28, but I know that each version was "good enough" as of a particular moment.
One time I decided to delay a book by a week so I could change a comma to a period and uppercase the next letter. I doubt that anyone else would have noticed the perceived imperfection -- but I could not let it be.
I started writing Typography for Independent Publishers back in 2012. I wrote about 400 glorious pages and then -- for a reason I no longer remember -- I stopped working on it.
Last month I looked at the file and realized that I had written something really good that deserved to be published. I started feverishly editing and adding -- tweaking, in other words.
I uploaded it to Amazon at the end of January. It has consistently ranked in the Top One Hundred ebooks about book design although I've done no promotion and have not sought any reviews.
I'm still tweaking. It's getting better and better every day. It's not quite ready, but if you buy a copy now instead of a few days from now I will not be embarrassed by what you'll read.
