愿心欣
转眼间, 假期就快结束了,没太多的感触。我想这有别于以往,那期代从新出发,与朋友“小别重逢 ” 吧。这段时间, 发生了点事。。。目前暂且保密, 但有的时候还是觉得矛顿。人啊~真想叹气。。我到底在干嘛。。那种一发不可收拾, 被动的往前走。 早已忘了为什么当初这样。令人小小开心的是大学同学之间还有保持联络。。偶而的小聚会常让人感觉到很兴奋。朋友真的无价。我想我也不应该太钻牛脚尖, 要看开!知足常乐~努力调适吧!!!

Tradeoffs
happiness+sadness= K, where K is a constant
by weiling's law, happiness cannot be created nor destroyed
it can only be transferred from one person to the other
--thats why
Let Happiness =1 and Sadness =-1
E(Happiness)= 0.5(1) + 0.5(-1)= 0 if the sample size is large enough.
