Famous Leaders

In what ways do the lives of great leaders show a mixture of achievements and setbacks?  Do you think less of leaders who show weakness or encounter failure? I believe that the lives of a great leader show a mixture of achievements and setbacks. A great leader in my opinion would have to be Martin Luther King. He brought together the people, and also had a very famous speech "I had a dream". Martin Luther King had so many achievements most dealing with getting equal right for everybody regardless of color, and race. With Achievements there are also setbacks. Some setbacks were things like when people would not agree with him and his goals weren't reached, but in the end Martin Luther King reached all of his goals and is an inspiration to many today.
