Still doing it, but the pandemic forced me to stay in one country for just about a year now.
In that year I put down roots, got long term visas and maybe will spend another few years there while we see how things shape out this and next year.
But ya, 2-3 months minimum in a place is what you need, with just a small backpack.
Make local friends.
Don't hang around or go out with other tourists or expats. This is the kiss of death.
Make it a rule to eat only the food of the city or the country that you find yourself in.
Learn a few words of the language "hello", "thank you", "bathroom", "stop", etc.
Don't think people are less than you. They're not. They want the same things as you.
As an introvert, being forced to make friends with people who speak another language and look the opposite of me (black guy in Asia), was exactly the ticket.
Well recommended to do it.
The main thing I would say - is have a mission when you travel. Seeing the sights and drinking the bars and mingling with other tourists and shtupping the local girls is fun, but not a mission.
You will get bored after some time of doing that.
Have some particular work or meaning to each day to keep you grounded, and you can do the moving around for a super-long time.
You will find that you'll set some schedules for work, play and discoveries - regardless of where you are.
Just don't quit your job. Instead go remote (even if you have savings). Ok?
