If anyone knew what it meant to overcome adversity and achieve greatness despite obstacles, it was the 32nd President of the United States, Franklin D. Roosevelt.

When he was paralyzed by polio at the age of 39, most experts concluded that his promising political career had come to a screeching halt. Undeterred, Roosevelt defied the pundits and rose to the top of his profession, eventually holding the presidency longer than any person before or since.

His attitude toward obstacles can be summed up with his response to a person who said, “Mr. President, you can’t do that.” Roosevelt replied, “I’ve done a lot of things that I can’t do.”
