It's the little bits of progress that make up the grand picture, my ducks.
We are coming ever-closer to the hand-in date, and we *must* continue working (hence the reason for creating the progress thread). We will all go through moments where we doubt ourselves, but you have to remember to have some faith in yourself. At some point in time you believed you had a concept worth expanding upon, and likely it is still very much worth it.
If you do truly feel you have gone slightly off-track from where you intended, it is not too late to salvage what you have and rework it in a slightly different direction without actually having to change too much. Do not underestimate the power of reworking - with minor changes of tone, structure and wording, you can create something entirely different without "wasting" all your previous work up till now.
I hated my first full draft. I really did. I'd tried so hard, but it just wasn't coming across like I wanted it to, and you could see it. Reworking changed all of that. I honestly thought it would never turn out ok, but it did, and I'm not the only one to have gone through this scenario. Do not give up! There is always another way of doing it.
