Martin Nash, the charming cheat, held a Farewell lecture. I was lucky enough to join. To my surprising, there were not much people attended. He was awesome, when you watch him performs, you see an elegant move and Martin have reasons for all of them. "You should do this becuase...", I learned a lot. He was saying, one should add one's own personality to the performing. How to deal with such and such. For example, what to do when you need to mosit your hands.
