4. You'll learn about yourself
If you're doing it right, a trip to a new place should push you out of your comfort zone. Imagine how far out of it you can get when there's no familiar face around. If (when) you miss your bus or get lost, you'll have to depend on yourself to resolve the situation. You can learn a lot about who you are in those moments. If not, there's always Google maps - thank God.
