The opening paragraph of Jean Fritz’ biography Bully for You, Teddy Roosevelt:
What did Theodore Roosevelt want to do? Everything. And all at once if possible. Plunging headlong into life, he refused to waste a single minute. Among other things, he studied birds, shot lions, roped steer, fought a war, wrote books, and discovered the source of a mystery river in South America. In addition, he became the governor of New York, Vice-President of the United States, then President. This was a big order for one man, but Theodore Roosevelt was not an everyday kind of man. He was so extraordinary that when people tried to describe him, they gave up on normal man-size words. ‘A cyclone,’ that’s what Buffalo Bill called him. Mark Twain said he was ‘an earthquake.’ He was called ‘an eruption,’ ‘an express locomotive,’ ‘a buzz saw,’ ‘a dynamo.’
