Part of our fear of midlife change is the fear that we are somehow abnormal. From our limited perspective we think that our friends' lives remain stable. Only we seem to be spinning out of control on a fast-changing globe. Change is not only normal, it is necessary. Change is necessary.
Biologists call it natural selection.
Those organisms that are not able to adapt to change cease to thrive in their environment. Eventually, they die. Similarly, successful midlifers will learn to change with change. The best workers will be those who are willing to learn new skills. The best marriages will be those where both partners grow and expand their horizons, and the best parents, those who are willing to assume a new role with adult children.
