You've successfully completed a task. Sure, that's important. Obviously. But if the goal of writing the book is for others to read, perhaps even to sell X (e.g., 500) copies then there's a very good change you will not reach that goal.

That's ok. That's the point. That's the norm. So if you come up short, so what.

My point is, maybe labelling everything you do a failure is not that good for you, mentally. I think this is somewhat ingrained in US culture, and I wouldn't be surprised if this is at least one of the causes for the mental health crisis in the US.
