This is now laminated and stuck above my monitor. I didn't realise how much happier I am when I'm writing regularly until I started again. OK, I'm not producing anything that I'd post without editing, but I probably shouldn't be doing that anyway. And it's much easier to keep going when I just skip to the next idea every time I reach the end of wherever I've mentally planned to.
Thanks to everyone to who replied to
this post. It really helped me get started again.
