Okay, so I get that even the sharpest query letter will get rejected to some percentage. I'm still plodding away knowing that. But after getting a few rejections (7 and counting so far), I'm starting to get paranoid that my query letter is problematic and should be revised, even though it went through query letter hell and got some generally constructive feedback and even some positive reviews. I guess my question is at what point do you hit the pause button and dramatically revise the query? Or do you just keep going?
