I'm a big fan of the notebook idea. Not only for random poetry or venting frustrations, but for questions to... well, to no one, but I suppose to myself, or maybe to the universe. It is, I think, a good way to remain objective and not instantly grow angry/annoyed at things we don't entirely understand.
"Hmm... everyone is spitting there. Why is that?"
It is also a nice way to remember things that we are curious about when we meet someone who is open to answering such questions.
"Hey.. question, I noticed everyone is spitting on the train this morning. Why do they do that?"
I have been keeping a daily memobook since I came to Japan, so that is well over a decade of questions.
I'm looking forward to #randomchina!
