Sometimes it's hard to walk away from a project that you have already poured that much work into. It's like the sunk costs fallacy, except not a fallacy really, just wanting to see the results of your labor. Even if it requires more labor before you get to see them. Even at work, when I have been put on awful, backbreaking projects with insane deadlines, and then just before the deadline (a day or two) they have said, "Oh, you won't get done in time, just suspend the project," or "Oh, this is going on with our partners, suspend it," and so on, I have found that experience incredibly frustrating. From the day I received the project until the day it was put on hold I worked very hard to provide valuable work, feedback, and results. Even when suspending the test means I don't have to kill myself at work for the next 24 hours, it's frustrating to pour everything I've given my all to already down the drain.
