It’s okay to have nostalgia for places, people, activities, and things you enjoyed.
You don’t have to challenge your nostalgia. But neither should you assume nor insist that the experience will produce the same feelings in others. They have their own nostalgia.
Your feelings of nostalgia are real whether or not the original experience was objectively good.
Focus, instead, on fostering new nostalgia with fresh experiences and on bringing others along for the ride.
Shared nostalgia is the sweetest nostalgia.
