Othyrsyde, I firstly want to say that I'm sad to hear that you're feeling like you might need to put this on hiatus for a bit. I've been enjoying reading the updates when they come out sporadically (even though I have to re-read it from the beginning each time because I've totally forgotten what happened in the previous update from the one that came before it). Secondly, though, I want to say that this is totally your project to continue, reboot or not continue, at your own discretion. I don't believe in trying to convince you to continue it because, frankly, if you're not enjoying writing it, then me asking you to continue for my sake would be unfair to you.
However, I do want to say that the discouragement that you're feeling sounds a lot like discouragement I've experienced in the past. Well, specifically, that the more and more time I spend on Donnacona's Dream, the more and more I want to go back and change what I've already written. Specifically, your own advice that you gave me about trying to incorporate more indigenous-language words has inspired me to try to recreate Kanatian/Laurentian place names, but has also made me cringe at the place names that I used in the first few updates (which were either French-derived, direct translations, or overly simplistic)... But, I know that if I went back and edited posts now, I'd end up writing everything in more detail, and it would be a year before I'd even be at 1600 with the reboot. And I'm really, really, interested in where I'll end up by 1700. So, I've decided that I'll save all the changes I make for later, when I decide it's time to create a "Finished Timelines and Scenarios Version", and for now will accept the fact that I'm writing a TL in which my writing style and depth of research have improved substantially as the TL has progressed.
Anyways, hope that wasn't too rambly. I guess my point was that I feel like I can empathize with where you're at now, and that my way out of my own similar situation was to stop being my own worst critic, to keep on writing and to put off revisions until the indefinite future.
