For this week's Curiosity of the Day, I wanted to do something different, so I consulted the Chinese I-Ching (易經, YiJing, the Book of Changes) instead, to reflect what we need to know for the week to come. I-Ching Hexagram 16 is Yu (豫), in a glance it represents enthusiasm and a carefree life, however there're other messages hidden inside once we interpret each trigram separately.
