夜很黑，我远离家乡。
最好的数学是简单的，但又不至于过于简单。
From time to time you may stumble， fall， you will for sure， count on this， no doubt， you will have questions and you will have doubts about your path. But I know this， if you’re willing to listen to， be guided by， that still small voice that is the G.P.S. within yourself， to find out what makes you come alive， you will be more than okay. You will be happy， you will be successful， and you will make a difference in the world.
