Good list! Some of mine are:

-accept and embrace that things will sometimes not go according to plan

-use street smarts and common sense

-for more authentic/less tourist food, avoid places that have a person trying to corral you into them, have pictures on the menus, and have a separate English menu (though the last one isn't always a sure thing)

-force yourself outside your comfort zone as much as possible to have the best experiences and more growth

-don't make yourself a target by wearing flashy and expensive things, displaying wealth

-always know what time the metro stops in the city you're in. Coming from NYC where the subway is always running, it's something I sometimes forget about 😅
