When someone is made the head of an office in the Ogilvy & Mather chain, I send him a Matrioshka doll from Gorky. If he has the curiosity to open it, and keep opening it until he comes to the inside of the smallest doll, he finds this message: If each of us hires people who are smaller than we are, we shall become a company of dwarfs. But if each of us hires people who are bigger than we are, we shall become a company of giants.

Ogilvy on Advertising, p. 47
