25. Theodore Roosevelt
President: William McKinley, 1901
State: New York
If you ever want to feel like you’ve utterly wasted your life, look to Theodore Roosevelt. By the age of 42, he was already a war hero, a respected author, a cowboy, a governor of New York and a Vice President. Then, after William McKinley's assassination, he became the youngest president in American history. For fun, Roosevelt reportedly read two books a day and enjoyed skinny-dipping in the Potomac during winter.
