It’s less about age and more about our ability to take care of our responsibilities. As children, we have few, and taking care of them takes little time and is easy. As we grow we get more and more, and if our abilities don’t grow in tandem we become stressed and unhappy. It’s easy to find yourself in a situation as a young adult where you have lots of responsibilities and not enough time, money, and training to discharge all of them. Similarly in middle age if you haven’t kept upskilling and you find yourself outclassed professionally by younger professionals.

Some ways to fight this are by keeping your lifestyle simple and inexpensive; by constantly seeking to improve; by being parsimonious with your social commitments; and by building a network of mutually supportive friends and colleagues who can help you during sudden spikes of need or sudden dropoffs in ability, such as unexpected illness.
