Don't I know it! Haha But I've loved every minute of it. I was very blessed when I got her..she is sooo easy going, very smart and gets things RIGHT away.
Lunging is very useful, I don't see why you couldn't try that sometime soon. I've also done alot of ground work with my baby...teaching her to back up on command, bend her head, move on the forehand and her hindhend, to stand. And alot of desensitizing her to different objects.
If you ever have any little questions, I could try to answer them since we're pretty much in the same boat! :)
