Thanks to everyone who participated in the discussion with Dave King. I hope you all found his answers helpful.
During this discussion, Debra brought up an interesting point about receiving criticism of our work.
It can be overwhelming to receive so many conflicting opinions. When that happens to me, I'll simply read through the advice and set it aside for a while. Then I'll come back to it after a few days. Keep in mind, any feedback on your work is simply "advice." That means, take it or leave it. If I get three people that mention the same "problem," then I consider changing it. But if it's just one person and no one else, I ignore it--unless it's something that really speaks to me. In the end, go with your gut. I've seen several writers lose their voice (and their passion for writing) when they've tried to please everyone. You're not going to please everyone. That's just the way it is with "art." :-) Even bestselling authors receive criticism, and sometimes hate mail.
How do the rest of you deal with criticism/feedback on your work?
