If you have no kids and can move anywhere where do you go? Near friends? Near family? Your’s or your partner’s? How long can you tolerate being a nomad? How do you set expectations when arriving somewhere new?
And that’s just on the personal side. How do you deal with international work laws? Do you pass off as a contractor? Do you stretch the lines of being an employee in one country while spending as much time as you can outside that country? Do you commit to having to travel frequently to keep it legal? Do you dive into local work law and adapt as you move? All these sound pretty terrible to me.
