Gary Kremen, founder of Match.com with a self-estimated net worth of $10 million in 2007, logs 60- to 80-hour workweeks because he doesn’t think he has enough money. He says to the New York Times:

Everyone around here looks at the people above them. It’s just like Wall Street, where there are all these financial guys worth $7 million wondering what’s so special about them when there are all these guys worth in the hundreds of millions of dollars….

You’re nobody here at $10 million.

Another millionaire, Umberto Milletti, says, “Here, the top 1 percent chases the top one-tenth of 1 percent, and the top one-tenth of 1 percent chases the top one-one-hundredth of 1 percent.”

You can play the game—and win—and still feel like you’re losing. When you define what success is, and what enough means to you, you earn the freedom to walk away from the game. 

Incentives make for a great servant and a terrible master.
