If you come to think of it, you never see deer, dogs and rabbits worrying about their menus and yet they run much faster than humans.
Emil ZatopekWhen I was young, I was too slow. I thought I must learn to run fast by practicing to run fast, so I ran 100 meters fast 20 times. Then I came back, slow,slow,slow. People said, 'Emil, you are crazy. You are training like a sprinter.'
