" When you believe that stress is harmful, anything that feels a bit stressful can start to feel like an intrusion in your life. Whether it’s waiting in line at the grocery store, rushing to meet a deadline at work, or planning a holiday dinner for your family, everyday experiences can start to seem like a threat to your health and happiness. [...] These are normal and expected parts of life, but we treat them as if they are unreasonable impositions, keeping our lives from how they should really be. "
