3. A Chance to Try New Things
"Do not follow where the path may lead. Go instead where there is no path and leave a trail." -- Ralph Waldo Emerson
While you may branch out at home with new restaurants from time to time, traveling kicks you out of the comfort zone and forces you, for better or worse, to try new things! Even if you don't enjoy your first attempt at scuba diving, at least you'll be able to relate in a new way the next time you see it in a movie.
Becoming a well-rounded individual enhances self confidence and will help you with new material for conversation in social settings.
Who knows, you may accidentally discover your new favorite food or find out that you want to pursue a new career in karaoke.
