First, as people grow older they tend to become slightly more boring versions of their younger selves. Their agreeableness and conscientiousness goes up, but their openness to new experiences goes down. We call this change psychological maturity, but itās really a euphemism for boring.
Second, when leaders change, they tend to become more exaggerated versions of themselves. Niche picking, the psychological principle that explains this tendency, concerns our natural inclination to seek out experiences that are a good fit for our personality. When we do look for these familiar, preferred activities, our proclivities are strengthened. For example, extraverted leaders will seek out situations in which they can connect with new people, be the center of attention, and behave in more upbeat and energetic ways, and those situations will, in turn, make those leaders more upbeat and energetic and better at both connecting with others and performing as the center of attention.
