Martin Luther King, Jr.: Move forward!
If you can't fly then run, if you can't run then walk, if you can't walk then crawl, but whatever you do you have to keep moving forward.
Martin Luther King, Jr., (January 15, 1929 - April 4, 1968) was an American pastor, activist, humanitarian, and leader in the African-American Civil Rights Movement. He is best known for his role in the advancement of civil rights using nonviolent civil disobedience based on his Christian beliefs. He was born Michael King, but his father changed his name in honor of the German reformer Martin Luther. A Baptist minister, King became a civil rights activist early in his career. He led the 1955 Montgomery Bus Boycott and helped found the Southern Christian Leadership Conference (SCLC) in 1957, serving as its first president. With the SCLC, King led an unsuccessful struggle against segregation in Albany, Georgia, in 1962, and organized nonviolent protests in Birmingham, Alabama, that attracted national attention following television news coverage of the brutal police response. King also helped to organize the 1963 March on Washington, where he delivered his famous "I Have a Dream" speech. There, he established his reputation as one of the greatest orators in American history. On October 14, 1964, King received the Nobel Peace Prize for combating racial inequality through nonviolence. In the final years of his life, King expanded his focus to include poverty and speak against the Vietnam War, alienating many of his liberal allies with a 1967 speech titled "Beyond Vietnam".
