Are you able to write something, and it just doesn't feel like it? Don't throw those away; take a break and return after a few days. You might find that what you wrote is actually good.
Or if you're tired, take a rest, then return to writing.
my end goal is re-writing the part of the story that is already done to make it better, just for myself and gathering some people who could be interested in my stories... although some other ideas are currently turmoiling in my head
