You Learn to Be Flexible
When travelling, especially in new countries, you step out of your comfort zone and are forced to adopt to new customs and societal differences. This challenge “opens” your personality more, noted a 2013 paper by Zimmerman and Neyer. New societal adaptation calms your emotional reactions to changes in the day-to-day and boosts emotional stability, their paper concludes. At the same time, you meet new people, expand the size of your existing social network, and fortify your sense of congeniality.
Tip: Charm the locals you meet by learning and expressing, from time to time, typical expressions and idioms of the culture. Punctuating your phrases with a word of curious note will endear you to them.
