Ken Griffin, founder of Citadel, has a $10 plaque behind his desk that reads: "If we're all going to eat, someone has to sell." Of all the things this man could surround himself with, he chose a cheap plaque with a blunt truth about business. "You're always selling. You're selling to candidates. You're selling to vendors, you're selling to counterparties, you're selling to customers." And if you're always selling, you know what you're going to hear a lot of? "No." Griffin doesn't sugarcoat it. He tells two stories that illustrate just how brutal rejection can be. 1994 was a rough year, with Citadel losing ~4% of its capital. Griffin flew to Switzerland for a crucial lunch meeting, sat down, and his guest arrived only to say: "Oh, I thought you were John Griffin from Fen Church. I got to go." His lunch date got up and left the table. Later that afternoon, a Swiss banker spent 45 minutes with him in a beautiful office, smoking a cigar, before closing with: "Such a pity that such a bright young man picked the wrong career." Two rejections in one day for the founder of one of the most successful hedge funds in history — and his takeaway was simply this: "You just have to tolerate. You're going to hear no a lot, but you need to become accustomed to having to market your ideas and market what you represent and what you stand for." Absorbing rejection and continuing anyway is the actual skill, whether you're hiring, raising capital, or winning customers. Most people avoid selling because they're afraid of no. The ones who build great things have learned to expect it.
