Feedback

I've learned feedback is pretty much the best thing for any writer.  Last night I talked on the phone with my Uncle (who's also trying to get published) about different problems that I've been having with my stories.  Like how I have to start over with Kayza.  I'm a little nervous to start that again, because I don't want to end up rewriting again.  So talking with someone who's currently rewriting as well helps me a lot.  What do you guys think?  Do you like your work critiqued before you finish it?
By the way, here's  a song that I've been listening to lately.  Completely unrelated and a little sad, but I love it!
