True that. But, in this case (and many others), the decision is impacted by both the sunk cost fallacy (your point), but also the "I don't like looking at that mess I made so let's just throw it out" fallacy. Just because it makes you feel bad looking at it, doesn't mean throwing it out is the best answer. Sometimes, jumping in and spending the time is the best answer. Of course, if there's a rule for how to avoid both of those errors, I haven't found it. But it's helpful at least to know that they both exist.
