2. Find a remote job in US. Even a junior position with a low salary would allow you to live decently in most European places (maybe except downtown London, etc.).
3. Pick a random European city you might like, get an airbnb and just go there for a while.
4. If you like it, stay. If you don't, pick another city. If you can't make the decision in 3 months, move to a cheap place in Asia and go back when you can. Flights are cheap. Places to stay are cheap. Just lower the bar. You don't have to live in the middle of Paris or London this whole time.
5. Travel a lot and profit. Unless of course your prefer to go through a routine of choosing a single place, finding a job in there, networking, making lots of new friends, etc. There's your tradeoff, but hey, you are 26.
