It's often hard to shelve a project for a while due to other commitments. I was pretty busy for the later half of this year with one workshop after another. It can really 'kill' the creative aspect of something if you have to stop for a while, so it's taken me about a week to get back into editing the book and reviewing / correcting the text and maybe revising paragraphs where I felt the flow wasn't flowing or where I had been so vague that even I, had no idea what I was writing about.
So now I'm pretty much finished, I've just got to get it proof read by a few other people including a technical author, a journalist friend of mine who does this sort of thing for a living and also some very kind friends who're very enthusiastic about what I do and have been immensely kind so far with their help.
So I feel all geared up to continue writing and I have some other ideas / projects that have been in a state of incompletion for the best part of six months too.
