About a week or so before each trip, make a mental list of items that you don’t want to forget.
Taste a bit of everything when you travel, especially if you don’t know what it is. Ask local people for recommendations. Eat street food from vendors with big lines out front.
You may only see these places & meet these people once in your lifetime. Remember them forever with plenty of photos. Don’t worry about looking like a “tourist”. Great photos are the ultimate souvenir.
A simple “Please,” “Thank you,” and “I’m sorry” in the local language goes a long way.
Don’t miss that epic sunset photo spot after you realized your phone battery is dead!
A medical emergency can wipe out your savings, have an Insure t have you covered from medical expenses.
Do not get stuck seeing the usual touristy places. Be explorative, travel local and that’s the best way to see a new place.
