Editing and commitment issues

I have become fickle in my middle age and seem to have developed commitment issues.
I'm talking about my writing of course. Whilst the film stuff is all chugging along nicely, The Novel has stumbled again. Having taken a little break from my Banshee novel, re-reading it plunged me into despair - so many plot holes, clichéd characters and saggy bits. And I do find it difficult editing my own work at the best of times.
So I am cheating on Banshee with Dorcas Grubb, a former lover I set aside a few years ago when I decided I wanted to write a novel for adults. So with Dorcas I have a story of just under 50000 words for 10-14 year olds that needs a new middle. 
I have also started on a new piece I have been toying with for a while called Three Sisters that is a YA novel set in the village of the title, which blends fairytales and myths with present day village teen life. With family feuds. And Grim Reapers.
My writing routine is improving, and I am hoping to finish the new version of Dorcas by Christmas. I'm sure nothing else will distract me before then...
