I try not to let it get me down, but sometimes it does. Even though I've been pretending ever since I sent out my query letters that it doesn't matter so much. I can always write another novel (yeah, in another four years). Here are some thoughts about how to ease the sting of a rejection:
1. Do something creative with the rejection letters, like give them to your new puppy and see what he thinks about it.
2. Read blogs about rejection written by other writers. It helps to know there are others out there feeling the same way.
3. Twizzlers. Chocolate. Whatever. Treat yourself to something delicious.
4. Send out more queries. One letter is just one person's opinion.
Actually, the thing that works best for me is to immerse myself in a new and even better writing project. I'll go back and fix up the rejected one someday, but the more writing I do, the more my writing will improve (especially with my awesome critique buddies to give me feedback). The next book I write could be The One.
What's your best tip for dealing with rejections?
