If you mean the president’s characteristics, he was very patient because everyone and everything didn’t change for the better immediately. He was very diligent because he brought several programs like the CCC or the AAA (and many more). He also did fire side chats in order to connect with his people and make them feel better about the situation at hand.
He, as a pragmatist, used pragmatism to address the Great Depression. As Roosevelt said, "It is common sense to take a method and try it. If it fails, admit it frankly and try another. But above all, try something." That is what pragmatism is. Pragmatists test out new theories by applying them practically to see if they work. This, paired with his determination and quickness of action, brought America back again.
