One of the most interesting findings of a recent HBR article on team chemistry is that the types of people who become leaders within organizations are about 30% less likely than their coworkers to feel stressed out. As the CEO of a small investment firm, I was surprised by the finding, but as I considered my own leadership style and intraoffice relationships, I concluded that the authors were onto something. Plus, a finding from a 20,000-person survey is probably worth paying attention to.
