The world, gurus, coaches have made it seem like a bad thing to quit. There might be times quitting isn't the right option but that isn't always. There are times we have to quit. The project might just not be the right fit. There's no need to push hard and stick it out to see how things go. It's ok to stop, quit and move on. The longer you hold on, the more sunk cost fallacy will set it. It's ok to quit early. Take the lesson and move on.
