Ongoing means in progress, under way, continuing, being worked on. I have a novel that's been ongoing for years and now looks as though it will be more than one book (the big project I mentioned last month).
Insecure Writer's Support Group did what they're there for and offered support and encouragement. Amongst the helpful suggestions was a common theme – just go for it, do a bit at a time and don't put obstacles in my way. Since then I've added more words and am feeling just a little less daunted.
Other meanings of ongoing are progressing, advancing and growing. The story is doing that, albeit slowly. They're the aspects I'll try to focus on, rather than how much more there is to do and what might happen when I eventually finish.
This ongoing competition from The Third Word asks for just 80 words, which can be a complete story, scene or extract from a longer work. I won once and that was with a novel extract.
