I used to be puzzled at why people travel. After meeting several very interesting people who also love traveling, I started to explore this question.
Now that I have been to a number of places around the world, I wouldn't say that I have an innate desire to travel, but almost every trip has been rewarding. Rather than relaxing vacations, travelings are more like adventures to me.
I have been mostly traveling alone. It is a lot of work to make travel plans and book things. To save money, I stay in hostels with 4 ~ 20 roommates, and usually need to catch very early flight. Each time when I wake up 3 am in the morning for the flight, I ask myself, why am I doing this, instead of just having a good sleep? But the moment the flight takes off and seeing the landscapes from above the air, I'm already excited.
I think seeing how different parts of the world could be functioning in very different ways makes me a bit more open-minded. I read a lot during my trips, or sometimes I will do travel sketches.
