Q: if so, what advice do you have for other people who feel this exhaustion near the end of a project?
A: i make lists. go through and make a list of all the things that are bothering you or need fixing (focus on the biggest things first). then just go through and fix all those things. then go through and make another list, because now that you fixed what you fixed, smaller issues will pop out at you. you will always notice smaller and smaller things, but after about round 4 the things will be so tiny that it doesn't matter
