Meh, I can't relate, because I'm exactly the kind of person who does that. I'm always glad to see some humility in a writer, even if it's fake and just fishing for praise. Because see, most of us suck. It's nothing personal, it's just Sturgeon's Law. However, a great deal many of us are convinced that they are amazing, decent or just don't want to acknowledge there might be something negative with the story. And that's kind of silly. Because of Sturgeon's Law, odds are your writing sucks. Odds are *my* writing sucks. We can't all be the lucky 10%.
So it's nice when an author displays sufficient self-awareness as to realise that their writing is probably crap. Of course, if they don't really believe it, it's just a waste of everyone's time, but to me, self-deprecation instantly makes me like an author (and their works) a little more.
