I HATE the End
I hate ending stories. Short stories, novels, it doesn't matter. I hate ending stories and I think that's mostly because I -know- my endings are never as strong as my beginnings, and I hate that about my writing.
So I heard something neat about problems with your writing. Find writers who do it better, and then read them until you figure out what you're doing wrong and what they're doing right.
What's your favorite author in terms of endings? Books? Who writes killer awesome super cool endings that are so perfect you read the book again and again for the ending?! At this point, genre and style don't matter. The more varied the better, really.
