I'm not reading queries this weekend. Even the shark is taking some time to chew on Christmas pudding rather than hapless authors.
I do however glance at the queries I receive as I herd them into their little holding pen with milk and cookies. And I'm seeing a lot of this: "I don't know how all this works but..."
This makes you sound lazy and stupid. DON'T PUT IT IN YOUR QUERY.
Even if you don't know how all this works.
I know you're going to make mistakes. I encourage you to make many and try for more.
But, I also assume you've done some preparation before writing to ask I read your work. That maybe you've googled the phrase "how to send a query" (1) or "how book publishing works"(2) or "how to get a literary agent"(3) BEFORE you actually DO any of those things.
Would you show up at an NFL training camp and tell the coach you're not really sure how the game is played but could he watch and see if you're any good?
Would you show up at an audition for America's Next Top Chef and mention you're not really sure about the difference between bake, broil, simmer, and saute, but you'd still like to cook for them.
Would you audition for the New York Ballet and mention you aren't really sure what this whole five positions thing is but could they watch and see if you do it right?
Well, you certainly can of course, but it pretty much means you won't be taken seriously. Querying is not the first step. It's not even the fifteenth. You need to learn about the biz if you want to be part of it. This isn't just true of publishing. It's true of any business.
(1)my blog post is #4 on the list when you google this phrase.
(2) 20,900 places with info on this phrase.
(3) 2 MILLION hits for this phrase. It may not tell you everything you'll ever need to know but it's a good place to start--a lot better place to start than my incoming query mail for sure.
