The importance of communication is often overlooked. Despite our great prowess in communication, misunderstandings and mistranslations are commonplace. It is arrogant to believe that one can travel the world and expect all of mankind to understand his or her native tongue. In order to travel the world, whether for business or pleasure, a desire and willingness to adapt to new cultures and methods is necessary.
Adaptability, of course, includes the ability to communicate with new people in various dialects. Being unable to communicate in a country is akin to living with a serious impairment; it is very difficult and near impossible, to adapt and get along with new people if there is no way to communicate with one another.
