*Emotional intelligence is the recognition of your emotions, the emotions of others, how your actions influence the emotions of others, and how to regulate your own emotions. Ironically, by this definition, the author is the one lacking emotional intelligence. They didn't understand why they were angry, why others were frustrated or how to mitigate it. They still don't understand that just saying that you are at peace doesn't mean that you are. To me, the author is still brimming with hurt, anger, jealousy, greed, and pride, and because of these last three, I don't have much sympathy.
The common critique is not that the author made mistakes, it's that he's self-centered, a diva, etc for feeling like he deserves a huge chunk of the worth of minecraft for writing the end-poem on a contract. He thinks he should get more, people disagree because $20k is much more that you would have expected for such a thing anyways.
As an engineer, I understand the importance of logic, precision, and efficiency. But as an artist, I also know the value of creativity, expression, and intuition. These two ways of thinking are often at odds with each other, and it can be challenging for an engineer to understand the artistic mindset and for an artist to grasp the engineering perspective.
Despite the differences, both engineers and artists play important roles in the world and can learn from each other. By combining their unique perspectives and skills, they can create truly amazing things.
That said, even that is an oversimplification. There are lawyers, sales people, management, etc., thrown into the mix.
People are criticizing the post based on the cold hard mistakes the author made while completely glossing over the emotional introspection the author went through to acknowledge all their mistakes and finally close this chapter of their lives.
