Sigh. It must be a record. One was for Hedge Witch, from an agent. The other a very rapid response for The One Thousand, One Hundred and Eleven Keys to the Gates of Faerie.
One of the things I learned to do early on as a writer is to manage the inevitable disappointment of rejection. There are several strategies but a fairly simple one is to always have several pieces submitted to different markets at the same time. That way, it doesn't feel like all your hopes are dashed when you get a rejection. You still have other irons in the fire, other submissions that just might be successful. My advice would be to try and make sure you always have a good number of submissions "out there".
