I lived in Myanmar for two years and was later blacklisted and sent home. “The people” are not uniformly “full of joy.” In fact they appear to experience a full range of human emotions, as with everywhere except Silicon Valley.
Myanmar is an absolutely beautiful country. The people are full of joy and the food is amazing. I visited the cities of Yangon, Mandalay, and Bagan. We visited and meditated at many monasteries around the country.
