" People have marveled at the fact that I didn’t start McDonald’s until I was fifty-two years old, and then I became a success overnight. But I was just like a lot of show business personalities who work away quietly at their craft for years, and then, suddenly, they get the right break and make it big. I was an overnight success all right, but thirty years is a long, long night. "
