Here is something worth pausing on. In 1900, the average person's life expectancy was around 46 years. Today it is over 80. We live longer, get sick less often, travel more easily, and have access to more comfort and convenience than any generation in human history. By almost every material measure, life has never been better. And yet stress, anxiety and worry are rising. Surveys consistently report that more people feel overwhelmed, anxious, or burned out than ever before. Doctors see more patients for psychological symptoms than physical ones. Children are being screened for anxiety disorders at younger and younger ages. This is the central paradox worth sitting with: we have more, and we worry more. There is a useful distinction to make here. There is the kind of worry that motivates you to act on a real problem. You have an important exam in two weeks and you feel nervous, so you study harder. That worry served a purpose. Call it the useful kind. Then there is the kind of worry that generates stress and anxiety without producing any useful outcome. You replay the same bad scenario in your head for the fifteenth time and nothing changes. That is the kind worth paying attention to and doing something about. The goal is not to live without any fear or concern. That would be dangerous and impossible. The goal is to stop letting the useless kind run your life.
