By far the most difficult skill for me to learn as CEO was the ability to manage my own psychology. Organizational design, process design, metrics….. all relatively straightforward skills to master compared to keeping my mind in check. Over the years, I’ve spoken to hundreds of CEOs all with the same experience. Nonetheless, very few people talk about it and I have never read anything on the topic. It’s like the fight club of management: The first rule of the CEO psychological meltdown is don’t talk about the psychological meltdown.
