It's time to trust my instincts,
Close my eyes and leap...
I did. With my eyes closed, I pressed send right on the word "leap". (I did mention I'm a big dork, right?)
Anyway, I had originally started with just that one query as sort of a test, thinking that I'd wait to hear back (or not) before sending out any more. I was very concerned about unnecessarily blowing opportunities, which is exactly what happened with the first query. Once it happened, it didn't seem so bad.
I sent out four more queries last Saturday. On Friday night, I received a request for a full from an agent I really like!
Thanks to everyone who offered words of encouragement after my last post. You all were right.
