    Dreams are like stars. You may never catch them, but if you follow them, they will lead you to success. Yan Ning is such a dream follower.

Yan is a rising star in the science world. When Yan Ning was only a little girl, she dreamed of being a great scientist. After years of hard work, in 1996, she went to Tsinghua University to study biology. After graduating from Tsinghua in 2000, she went to Princeton University and finished her study abroad in 2007. Then she returned to Tsinghua and set up her own lab. At the age of 30, she became the youngest professor(教授)at Tsinghua.

    Now. Yan, 42, has become a leading biology researcher at Princeton. On April 30, she was included among the 100 new members and 25 foreign associates(院士)into the US Natinal Academy of Science(国家料学院)

    However, it was a long and difficult road for her to make such achievements. She said that in order to realize her dream, she experienced a lot of failures and pains. But she never gave up her dream. Instead, she followed her dream and fought for it.

    She usually works at least I4 hours a day. Sometimes she even forgets to eat and rest and works until late night. She never gets tired because she thinks doing research is the most "comfortable" job for her.

In a TV interview, Yan encouraged young people to work hard for their dreams. "All our dreams can come true if we have the courage to follow them."
