Middle adulthood, which roughly spans between the age of 40 and 65, is a time of significant changes in personality and personal development. People at this stage are often more self-confident and have a better understanding of themselves. They tend to be more concerned about the legacy they're leaving behind, and their focus may shift from personal achievements and success to contributing to the well-being of the next generation. They also tend to seek balance in their lives, attempting to equally divide their energy between work, family, health and personal development. This period can also bring about awareness and acceptance of aging, which can lead to shifts in personal priorities, values, and views on mortality. Lastly, the personality of people in middle adulthood is usually settled and consistent. However, they may also show openness to experience and appreciate more depth in relationships. They can be flexible and adaptive, leading to resilience and wisdom. But like any other stage in life, middle adulthood varies widely among individuals.
