It's hard to summarize what this is about -- China, asking the right questions, the future, how to live? -- but it's a beautiful and thoughtful read. One of those times when you read something from a stranger and not only think that you want to be friends with him, but that the friendship would bring out the best in you.
Fun fact: presumably I subscribed to updates from him at one point, for some reason, but I have no memory of doing so, and didn't know who he was, and still don't, apart from what I inferred from reading the letter.
So this was a lovely bit of randomness for me, and perhaps for you.
