Self doubt and agony

Okay, so I promised myself that I wouldn't allow myself to feel down about my rejections. Unfortunately, after updating my list of submissions to agents to include big fat NOs on the queries that I haven't received a response on for months, where I must assume rejection, my rejection rate has increased all the way up to an earth-shattering 18. Clearly, my query letter wasn't good enough to generate any interest. And, yes, after reading Noah Lukeman's How to Write a Great Query Letter on my nook, I see some glaring issues with my query letter. Time for a rewrite.
