Nostalgia has a bad reputation. Some people view it as unhealthy, a mental weakness signifying fear of change and progress. Many see it as a form of escapism, a feeling that people enjoy because it takes them away from reality and back to their youth. I’ve even heard it argued that nostalgia is bad for business, as companies need to focus on the present and prepare for the future, not dwell on the past.
A growing body of research indicates that all these intuitions about nostalgia are wrong. Reflecting nostalgically on the past is a common and healthy experience that helps people find the inspiration and confidence needed to move forward in life, particularly during difficult times. I would go so far as to say that nostalgia is about the future more than the past.
