Explanation:
Lincoln's Melancholy was a famous book written on the life of United States of America's first President, Abraham Lincoln. It was his biography showing his life and his struggle against all the odds in his life.
Lincoln higher purpose in life was to serve the people of America and and provide a good future to the citizens of America. He is considered to be one of the greatest President America had. This was his higher purpose to see a great Union.
Quote: As President, Lincoln argued his countrymen to accept their blessings and their burden, to see that their suffering had meaning, and to join him to a journey toward a more perfect Union."
I would like to recommend the idea of determination and self believe that is shown in this article by Shenk. Lincoln was very hard working and his country motivated him to achieve his dream of serving his country despite of all the suffering and failures in his life.
This is provided by the quote, " This is the story of a man who joined great pain and great power."
