Damn, this makes me think that just 13 years ago, we got one of Pixar’s best scenes, if not the best, depicting the opposite lesson.

Monster’s University had easily the most brutal, yet honest lesson of any Pixar film. A film that said that you can do everything right and still fail, but that there is always something around the corner that you may have never even realized. This movie tore down the whole MC is special message of these modern films and created a genuine masterpiece in doing so. I wish kids films were still this honest even if it is upsetting.
Wreck-It Ralph is also pretty underrated in this category. A film that leaves Ralph still in a pretty shitty job by the end, but with the benefit that now the people around him can see he has real value and appreciate him for what he does. God I miss early 2010s animation, so many worthwhile stories/lessons that got left to waste.
