Querying still...

I've been working on the query letter still. Read through it twenty times or more making changes. Sent it to my wife again, she gave suggestions. I took all of them, and can't find anything now. I sent it back to her just a second ago, but probably won't look at it again until tomorrow. Seriously, if you're trying to get published, you'll spend more energy on the query letter than any one page of your entire manuscript, yet, it is the first thing that lands on an agent or editor's desk, so you have to make it great!
