I've actually traveled a great deal (in my youth, including two years in Zambia and Kenya) and while it's not something I enjoy overall (for all the usual travel hassles, plus I'd rather spend my time earning money rather than spending it), I understand that your friend does. I don't know that there is anything particularly "perspective broadening" about it in a world that has grown so close together through technology and communication, but I'm sure she'll have plenty of memories and experiences from it. Memories and experiences don't necessarily have inherent value. They have personal value.

I enjoy working. I enjoy that every week, I get to do technically creative and very detailed and complex things with people who are all over the planet. China, Japan, India, Australia, all over the UK, France, the Vatican, Israel, Brazil, Canada, Germany, Singapore and many others. Granted, taking time away from work makes you look bad, so not doing that is a point in my favor -- but I truly enjoy my work. I also enjoy that it allows me to own a home, have plans to buy my childhood home so it can stay in the family some day, put my siblings through college, help with financial support and technical guidance of my friends' businesses and projects, contribute to worthy causes, and someday potentially retire.

Then again, if I have to die "young", I want to be one of those Karōshi deaths where they go out slumped over a pile of spreadsheets and whitepapers on their desk. So . . . take my preferences with a grain of salt, if you like.
