I've done the deed and sent my first revised version of my novel off to my agent.
Not an easy thing to do, trust me. I acted upon her feedback, taking heed of every single one of her suggestions and implementing all those I agreed with (almost all of them). Net result: a much stronger novel.
But are these things ever finished? I'm already fretting over possible mistakes in there, despite the fact I've given it several passes. Part of me knows I can only take this so far on my own, but the rest of me argues that it's me who's the main man pushing this thing forward...have I pushed it far enough?
Well, at least I can think about my other writing now. Back to this WIP which I sometimes think is better, sometimes think is worse, than novel one. The thing that's most exciting of all is the prospect of getting stuck in to novel three, which I have a complete outline for, and finishing off the bare bones outline I have for novel four. But getting to those seems a long way off right now!
