why is travel, or being "well-travelled" so admired?

I'm all for seeing new places, and experiencing new things, but only if I don't have other priorities, so going on out of town trips and spending money on the lodging, etc doesn't happen often for me, and I'm fine with that. I like the city I live in and quite frankly enjoy spending money here rather than the hassle of travel and doing similar things in another city
Travelling is seen as a fun and exciting way to spend your free time. It is also seen as a way to gain perspective and become more open-minded [1,2,3]. The more places you visit and the more diverse experiences you have, the more likely you are to succeed in business [1,2]. This is because travelling provides you with a wider range of social connections and a better understanding of different cultures [2,3]. It also helps you to become more organized and able to handle new situations [3,4].
People travel for many reasons. One important reason is that it improves physical and cognitive health [1]. It also exposes people to new cultures and traditions, and helps them learn about the differences and similarities between different lifestyles [2]. Traveling can also improve social health by forcing people to interact with and get to know people from different backgrounds [2]. Being well-traveled arguably makes people more well-rounded and open-minded [5]. It also improves creativity and physical fitness, because it requires people to be more flexible and resourceful in unfamiliar situations [3]. Finally, traveling can develop skills and confidence, because it often forces people to try new things and take risks outside their comfort zone [3, 5].
