The practice of nostalgia, or the experience of nostalgia, is an emotionally intelligent extraction of the past. It is a way of remembering the best of what was experienced, of remembering the Core or the Heart of what was experienced. And while it may seem silly, or superficial, or easily dismissed, Nostalgia is quite powerful in helping to remind you that while things may have been as bad as they were, there was always something of value at that time that contributed to what might be considered the good of your life.
