There are tons of countries I can visit without too much visa hassle (I'm South African). I work on upwork and though I'm 42 I live like a teenager, going where I please and getting new work or new airbnb, or moving to a new city or country when I'm bored. I have a wife so I don't get lonely, and I don't have or want kids so there's that.
It was a big leap to get started and I was poor in Costa Rica while I found my groove, but I can't see another lifestyle on the horizon.
