The three characteristics that historian Doris Kearns Goodwin believes were essential to the success of the 32nd President Franklin Delano Roosevelt were trust, optimism and communication.
Roosevelt exhibited these traits in that he came to power at a difficult time, when the Great Depression crippled the economy and negatively impacted citizens' hopes.
It was through his actions such as the creation of the New Deal, a project of high investment in the economic realignment of the USA, with the construction of schools, hospitals, hydroelectric plants and airports that he showed confidence and optimism in the country's future.
He also displayed communication skills by being the main spokesperson for the American people through the Atlantic Charter, which instituted a post-World War II vision, assuring values of freedom and peace.
