" Happiness research suggests that people are happier with their lives if they tend to hold a positive, nostalgic view of the past. Nostalgia is a universal and ancient human emotion and, today, academics across the world are studying how it can produce positive feelings, boost our self-esteem and increase our sense of being loved by another. This means that long-term happiness can depend on your ability to form a positive narrative of your life. "
