YMMV and it's certainly not for everyone. But I'm skeptical that staying in your comfort zone your whole life will do anyone much favors. (and the odd few week trip here or there doesn't really count, by all means all travel is great but vacation and just passing places through is fundamentally different from spending at least a few months or even years somewhere)
Isn’t that exactly what the comic is about?
I will say that I met my wife traveling and my kids were born on a different continent than me. There is a lot to find out there but travel as a value itself gets old and doesn’t fulfill your soul like it felt like it would when I was young.
