Darcy Pattison's blog has a bit today from an ebook called Nail Your Novel (just in time for NaNoWriMo). It's about how to read the rejections you get from editors.
I loved this line:
Persistence. The publishing world is full of tales of how our biggest literary stars just plugged away until they got their break. Persistence is vital. But persist intelligently.
Editors and agents do actually read each manuscript they’re sent – although goodness knows how as every day only contains 24 hours. Rejections are not effectively a lottery ticket that shows your numbers that didn’t come up. They tell you how you can significantly improve your odds.
Be positive about rejection – but don’t be idiotically so.
