From Shorts to Novels; Finishing What You've Started

So in terms of turning back I'm pretty much into the story now with 8,000 words done out of the target 40/50,000 and so it comes to the point of making sure that  I do in fact finish it. It's gonna happen, however long it takes! One thing I'm not keeping unique to myself, and something I've heard authors mention before in interviews is that you can start something and love it, and then during it for whatever reason the enthusiasm can start to lower a little. I wouldn't say I was at that point just yet, but I must say that the amount of words still left to write is a little daunting, but it's all part of the process, and I'm putting in some basic steps that I'm taking to ensure my enthusiasm for the story is as high as possible, and ditto for the productivity! So what are they? At the moment they are as follows:

1. Have breaks - Whether this is a couple of days, or a couple of hours, or even just a couple of minutes! On top of sleep of course, I believe breaks are essential, yes you want to get it done and yes you want to make the most of your creativity and your productivity. BUT without breaks your enthusiasm will inevitably lower and your creativity becomes a little stressed, because you're concentrating so hard and becoming tired. You also start to miss out little grammatical mistakes or rush through parts! 
2. Get feedback - You may not be done, it may not be your last draft of that particular selection but get feedback from friends or family on writing that you've done so far. If they like it, it will you give you more confidence to continue, and if they have negative opinion's it give you something to work on before you write the entire novel and then find out people don't like it!
3. Watch and Read - It may appear to be procrastination but its not. If you watch films and you read books as rest from writing your own, you'll have the get up and go to create something just as good, you'll have influence/inspiration from the author/writer/director and certain things might spark ideas! Keep the creativity alive!!
