Rejection

Got my first actual rejection from an agent query (usually they just ghost you). I'm not discouraged. I've heard how many rejections even famous writers have gotten. Trying to get an agent seems harder than writing the book. I've queried 21 but expect to query a couple hundred. Each one takes a surprising amount of time to find the right agency and agent within the agency and personalize the query letter. Each has different requirements, so I have different sized synopses, etc. I just changed my basic query letter because, as my friend, Mary, says, if an ad isn't working, pull it! If anyone feels like giving me feedback on my query letters or telling me which is better, it would be most welcome!
