521 Letters.

A few years ago, I wrote the same letter to: every head of state in the world, the governors of every U.S. state and territory, the premiers of every Canadian province and Australian territory, the CEOs of the United States’ 100 biggest “small businesses” and the world’s 100 biggest corporations, and the pope.

I asked each of them the same question: “What single thing is most important for a creative, self-employed person to do to ensure success in today’s world?”

I received 52 responses (a 10% response rate). Here are some of them.
