One piece of sound advice for those agent hunters (like me) is to never say any agent is your "dream agent." This can hurt the chances of finding the best agent for you, because other agents think, "What, am I chopped liver?"
The dream agent should be the agent you sign up with for years and years, who continually gives you satisfying deals, and communicates with you on a level you are most comfortable with. That means one author's dream is going to be another's nightmare.
Sometimes, however, I think we point to those agents who have an impressive list of best-selling books and label them "dream agent" much like we label George Clooney "sexy actor." Sure he's got good looks for his age, but would I even consider dating him? Yuck.
Now, my hubby is another story. He is the sexiest, most awesome man I know. (And you can't have him; he's mine!)
So, Writers... Dream-Agent Hunters, just be careful what you say.
I write about, with, for, and around kids all day. (Well, maybe I do the dishes too. Sometimes.)
