It's the details of a memory that provide its richness and meaning. Because [[memories unlock more memories]], the more details you record—the physical setting, how you felt, who you were with, the sights, sounds, temperature, and so forth—the more these details will trigger additional memories you _didn't_ record, and the richer the memory will be. The richer the memory, the better you'll remember it, and the [[Compounding value of memories|more overall value]] you'll gain from your trip.
