Whatever their differences, worrying and anxiety can both get in the way of living a good life. When you’re using your planning and problem-solving circuitry to worry, you can’t use that part of your brain for more important things, like excelling at your job or organizing a dinner party. It keeps you from focusing on what you’re doing and often makes it harder to connect with other people. Most importantly, it can be exhausting. Anxiety makes most situations feel more difficult than they need to be, which saps your joy.
