Does world travel make a person better than any other?

My best friend joined the military 3yrs ago. So far he's been to Texas for basic training, Mississippi for tech school, stationed in Germany, now in Korea and scheduled for Japan. In the past 3 years he has been more places, met more people and had more experiences than I have in my entire 28 years of life.

I fear that this will kill our friendship due to the fact that he's had a much more experienced life than me. I feel like he's probably gained culture that I simply don't have and is thus a more enlightened person. And I know that, in my life, I will never leave American soil much less the East Coast.

Is this an irrational fear? To feel inferior to those who travel?
