1. We spend too much time at hostels.
Hostels are wonderful (and cheap), but at the end of the day, they’re just full of other hostellers. So we end up spending all of our time with other expats and wanderers rather than with the locals in the place we’re visiting.
2. We think we’re the first people to see the world.
The time of my life when I was the worst person was right after I got back from my first study abroad when I was 20. I was insufferable. I thought I had the world figured out. But as I traveled more in my mid-and-late-20s, I began to realize that the more you travel, the less you understand. Traveling should be a humbling experience, not one that makes you arrogant.
