Roosevelt's 'Man in the Arena' passage -- from a 1910 Sorbonne speech titled 'Citizenship in a Republic' -- may be the most-quoted paragraph of American oratory. He was genuinely aphoristic ('Do what you can, with what you have, where you are'), a habit built on reading roughly a book a day and writing some 150,000 letters.
