> Take a flight to a random foreign country where you don't know the local language, and where most people don't know English. No hotel reservations in advance, no laptop, no smartphone, minimal budget. Figure out how to survive, have fun, and visit the city's major landmarks over the following 5 days. Bonus points if it's a developing country That sounds like a wonderful way to get kidnapped or murdered. Why do people recommend this? It seems only slightly less dangerous than going to the most dangerous neighborhood in the biggest city you can day-trip to, and start hurling slurs at passers-by. The rest of your advice seems wonderful and I'd highly recommend it!
