16. Obsessive photography
The obsession/obligation to document every street scene, statue and starter course kills the spontaneity and visceral experience that should be the backbone of travel.
It's now so easy to take photos that one click leads to another.
Before you know it, you have 300 pictures on your phone comprising old buildings, blurry sunsets and plates of food.
Congratulations. Your trip is now defined by low-quality images on a handset that, trust us, nobody back home wants to spend 20 minutes scrolling through.
