This is going to be condescending and all, but seriously do actually take an international trip. You'll realize a lot of things fall into the devil is in the detail. After going back and forth to Taiwan for over 18 years I can guarantee you that. I'm lucky for Taiwan where I can speak Mandarin (well reading is a different matter) and have family in place, but when we go to Japan where I'm less familiar with and my Japanese isn't as good, it's a hell of a lot of difference in terms of what you do. Especially during the times where the tour buses are going to a more rural / mountainous area and nothing is going on to talk about or whatever, except maybe car sickness if the road is annoying.
You want everything to be self reliant especially with the chance of losing small things.
That's a hopeful but still not a solution.
