bryanc_74 saidHow do you approach traveling alone?
I'm not sure I understand your question. Is it the travel itself, and how you are doing it, like flying or driving? Or is it the kind of destination you have in mind, and the kinds of activities there?
When solo, there are certain things I simply wouldn't do, places I wouldn't visit. For instance, Disneyworld or any amusement or theme park by myself is out. Those are things I'd only do with others. A cruise might be another thing to do only with a companion. But I'll go to the beach by myself, or go museum hopping (I love museums), do sightseeing, just walk the streets and look around, take photos (yes, I am a streetwalker). And like hauptstimme, until I got older I was a very fast walker, could cover a lot of ground very quickly, and having someone along held me back.
So the first thing I would suggest is itinerary, to match being solo. As much as you can, plan your vacation and your activities around being by yourself. Make sure you'll be doing things you would enjoy doing alone, assuming there are any (if there aren't any, I think this is all a moot point).
As already suggested, you can also rely upon tours. Either complete packages, or guided tours once you get there. I couldn't believe how much I enjoyed taking different tours of New York City a few years ago, when I brought my BF at the time there. I thought I knew the City pretty well, going there regularly since the 1950s, but the guided tours were fun and informative.
And I could see myself doing them alone, even though on that trip my BF was with me. A bus tour of Manhattan, a tour of Ellis Island, of the United Nations (about the only way you can see it), tour of Rockefeller Center and a separate tour of Radio City Music Hall, museums, etc. I befriended some Australians on the bus tour (they are the friendliest people, with that wonderful accent to our Yank ears), and was talking more with them than with my BF. So consider activities that include tours.
Other than that, it's a matter of having an independent frame of mind. I note your ethnicity is Asian. And while perhaps a cliche, many Asians are seen as being more social creatures than Europeans, a matter of culture (and of course I don't know how you were raised). So it may not be YOU per se, but rather your cultural heritage. That may be harder to overcome. Either you know how to enjoy your own company alone, or you don't.
