Which country is that? If it’s not a secret.

Spain. You can basically pick any continental coastal town, or any of their islands (Baleares or Canarias) and will find similar conditions. Portugal was (and still is) also an option for the future. For US citizens, I personally would look at Mexico, Costa Rica or Columbia, as those timezones are probably best when working with US companies. I am personally not a big fan of Asia (no offense to anyone), so Thailand was never on the list for me but I know it is very popular for remote workers.

EDIT: To add to this, you might not need to change countries if all you look for is to be more socialable/outgoing. A key factor here for me was the expat community - not because I want to live inside a little expat bubble, but at least within that community people usually moved away to another place to be more active/outgoing, make new connection etc. People don't expatriate to stay at home, commute to work, and watch netflix/play videogames all day. This could also work for you if you i.e. move to a more touristy/active area within your country, because a lot of options for active passtime such as outdoor sports attract people also for long term.
