Naw, novice ISTP superego use makes INFP grug. Poor ESTJ use is, like you said, the first big stress threshold, more an INFP behaving like an overly judgemental manager out of his element and finna pop a blood vessel because that's the best way they can adapt to the pressures, down tuning their Fi because they perceive it as a hindrance to the task at hand. Ideally you'd integrate it so you not only prevent sacrificing your strengths, but strengthen said strengthens and weaknesses. Simply as a communicative key, the ability to experience other mindsets within our lifetime allows us to bridge those opposites and find compassion and worth through understanding, even if it's understanding how little we understand with recognition of how much we want to.
