来週上海で２箇所、再来週北海道で3箇所レクチャーをします。全部違う話です。同じ話しは自分が飽きると言うのが大きな理由。何が人に訴えるかを知りたいと言うのがもう一つの理由。I will be giving lectures at two locations in Shanghai next week, and three locations in Hokkaido the week after. They will all be about different topics. The main reason is that I get bored of giving the same talk. The other reason is that I want to know what appeals to people.
