When I hear my inner critic I try to find something that we'll agree on. Most of the time it's a drabble or a PWP or just something that's silly or out of the fandom that I'm trying to write in at the moment. Other times I just lock the critic up and go look at my other stories that have received reviews. I think back and look at the comments, the positive constructive comments, not the negative ones and try to change my fic from there. When I look at other's fics and go "Wow I wish I could do that!" I just focus on the things I can do like smut, fluff, gen, family, and other things like that. I try to work on getting that better instead of writing a genre I know I would fall flat in. That normally makes the critic quiet down for a while.
