Sunk Cost

Another logical trap that costs us time and money: The Sunk Cost Fallacy:

It’s human nature. When we’ve invested so much into something, it becomes hard to quit if it’s not working out. It’s appealing to keep trying to make it work, even if it’s no longer worth our time.

One way to avoid this problem is to ask yourself whether you would start the project from scratch if everything you did got erased.

If it’s an obvious no, then you have your answer.
