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.
I tend to agree: it's really nice to build up experiences and "novel routines". But you can't do it forever, at some point this becomes a "meta-routine" that drains you (it's not easy to keep changing your life).
The idea that it's better to stay where you are and instead meditate and build up good habits is great and I subscribe to it, but with caution. It should not be an alternative solution to, say, escaping a toxic work environment or a bad place. You shouldn't "meditate away" real problems.
