I'm one of those guys who can look at a word, sentence, or paragraph and change it a thousand times. Then I'll come back to it later and still want to change it again. A thousand more times.
For a writer, that's the never-ending upstream swim with a WIP (that's sexy writer talk for Work In Progress). The trick -- if there is one -- is to know when to stop doing that and let it go, allow the "progress" part to halt, and just hit "send."
Most writers I know celebrate the send button.
That's very transmigrational, if you ask me. Celebrating the send button is an implicit affirmation of an afterlife, reincarnation.
I dread the send button. I don't care about afters or incarnations.
Oh well.
See ya, kid.
