Get rid of the sns things. No renren, no fb, no twitter, no qq, no douban, just msn, gtalk, google plus, tumblr, and weibo at night only.
I feel very irritability , don’t want to do anything although I know I have to keep hard working for my phd. And I need to control my weight, I need to do something instead of planning to do something.
Work hard and stay young. 90 again.
