Querying - Part Three - Sell Your Book!

Most writers suffer from Imposter Syndrome, and it attacks when sending query letters to agents.
Did I say enough? Did I say too much? Am I bragging? Are they going to roll their eyes and trash my submission? Why would anyone want to read my book?
That last question is the one your query must answer if you stand any chance of an agent requesting your full manuscript.
So pull up your socks and Sell Your Book! Polish your pitch until it makes YOU want to read the book. Send it to friends to see if it makes THEM want to read. Craft your bio to show yourself in the best light possible. Stay positive—even if you feel like you're wasting your time and should find a new hobby.
The worst thing the agent can do is say "no." Every debut author had their share of rejections during the querying process. Think about that. You are in the company of the greats!
So invest the time into crafting a confident query that screams, "You want to read my book!"
Querying would be so much easier if we could actually say that. 
And while you’re querying, keep meticulous records of your process. List which agencies you have queried, and which specific agent you addressed your query to. Note whether you emailed or filled out an online form. Include the date you sent the query, and the estimated time you should allow for the agent to respond (or ignore you.) Track your rejections.
This way, you will avoid the embarrassing mistake of sending to the same place/person twice. You will know how many queries you have out at one time, and who you need to inform if you get an acceptance. You will also know when to cross an agent off your list and move on.
Don't trust your memory. After you've sent a dozen queries, and you're preparing more, and a couple are rejected, they'll become a blur.
Keep it manageable. Your book doesn't need to be on submissions at 100 places at once. I have my manuscript out at six to eight places. However many agencies you choose to query simultaneously, make sure you stay organized. Know where your queries are and when you can consider them rejected.
And finally, persevere. All it takes is one “yes.”
