I recently came across an image which is sadly far too large to be sticking on here, but it told me that the Harry Potter series contained 1,090,739 words. I really hope that JK told someone how many words each book has and it wasn't just that some poor schmuck had to actually count each individual word. Why is this interesting you ask? Well I haven't done any math yet. There are seven Harry Potter books in all, and when you divide 1,090,739 by 7 you get 155,819 (not a precise number, there's a decimal point too). This means that on average a Harry Potter book is 155,819 words long. This is kinda disproportionate though because the first and second ones aren't too long and they didn't get long until about the fourth one.
The story I'm currently writing is, at the time of writing, 149,532. By the time you're reading this it will likely have surpassed the 156k mark. That's where this becomes interesting. I published the first chapter of that story on 28th April, of this year. That was about four months ago. In the space of about four months I have written a full length novel that continues to grow. I would not be too surprised if by the time this story had finished it was up to 200k words long. In fact if it wasn't for me choosing to split it into two separate stories for the sake of my own sanity and to keep a pure ending, then it would easily surpass that point.
I wrote a novel...in four months. I would actually be a little sad about this if it wasn't for the fact that the story is so popular and I've had so much fun with it. The reason I would be sad by the way is that it's a piece of fanfiction. It's not something I am ever likely going to be able to release or ever make a penny from. But, as I said, I am enjoying this story. If it wasn't as popular as it is it actually would not be this long at all.
At the end of the day I can say to myself that I wrote an entire freakin novel in four months. I'm a writing machine. If anything I can even take it as hope for down the line, and once this is over and I'm back on Immortal Space it's something I can take away. I have a seemingly incredibly high writing output. 6k words a week doesn't seem like much, neither does working on a story for four months, but when you take a step back and look at it like I have, then it's a pretty sweet thing I've gone and done.
