Traveling is as much about experiencing new modalities of life and learning new skills on the way. You are improving your personality every time you step outside of your comfort zone and experience new and exciting things.
When I moved to Norway I was forced to learn Norwegian because my colleagues did not speak any English. When I traveled to Bulgaria, I had to learn how to live on cucumbers and cabbage on daily basis, when I went to Romania, I learned how to hitchhike. Traveling makes you learn new things wherever you go.
