Aung San Suu Kyi winning a Noble Peace Prize was very important. She fought nonviolently by creating the opposition party, the National League for Democracy, to make a stand for the freedom of Burma. She was put in house arrest for 16 years to stand up for Burma and its people. She made many personal sacrifices during her stand which included not being allowed visitation between her and her family, and eventually missing the death of her husband in 1999. She would not withdraw from politics nor give up the chance to free Burma.
Her son quoted in her speech that "She would say that this prize belongs not to her but to all those men, women, and children who, even as I speak, continue to sacrifice their well being, their freedom, and their lives in pursuit of a democratic Burma." It's important that she believes that all her work and sacrifices will help Burma become free, not that just herself will be helped. Her selflessness is very admiring and stood out to me.
Since November 2010, Aung San Suu Kyi has been released from house arrest and is still involved in politics.
