Teammate Jimmy Piersall once asked him why he was so mad all the time. Williams responded, “You know why? Because I’ve got to be good every day. You … - Eric Barker

But Bernstein says this is a trap. Explaining is almost always veiled dominance. You’re not trying to educate; you’re still trying to win. The subtext is, “Here’s why I am right and you are wrong.

"Jeff Hall's research found that it took as many as sixty hours to develop a light friendship, sometimes one hundred hours to get to full-fledged "friend" status, and two hundred or more hours to unlock the vaunted "best friend" achievement...

Hall also found that how people talked mattered. We've all hit that wall with a potential friend where the small talk starts to go in circles...

Want to make good friends without the dozens of hours?... Arthur Aron got strangers to feel like lifelong pals in just forty-five minutes. How? Well that leads us to our second costly signal: vulnerability."

Two men have died trying to do this. Outside Magazine declared the Race Across America the toughest endurance event there is, bar none. Cyclists cover three thousand miles in less than twelve days, riding from San Diego to Atlantic City. Some might think Oh, that’s like the Tour de France. They would be wrong. The Tour has stages. Breaks. The Race Across America (RAAM) does not stop. Every minute riders take to sleep, to rest, to do anything other than pedal, is another minute their competitors can use to defeat them. Riders average three hours of sleep per night — reluctantly. Four days into the race and the top riders must debate when to rest. With the competition tightly clustered (within an hour of each other), it is a decision that weighs heavily on them, knowing they will be passed and need to regain their position. And as the race goes on they will grow weaker. There is no respite. The exhaustion, pain, and sleep deprivation only compound as they work their way across the entire United States. But in 2009 this does not affect the man in the number-one spot. He is literally half a day ahead of number two. Jure Robič seems unbeatable. He has won the RAAM five times, more than any other competitor ever, often crossing the finish line in under nine days. In 2004 he bested the number-two rider by eleven hours. Can you imagine watching an event during which after the winner claims victory you need to wait half a day in order to see the runner-up finish? It’s only natural to wonder what made Robič so dominant and successful in such a grueling event. Was he genetically gifted? No. When tested, he seemed physically typical for a top ultra-endurance athlete. Did he have the best trainer? Nope. His friend Uroč Velepec described Robič as “Completely uncoachable.” In a piece for the New York Times, Dan Coyle revealed the edge Robič had over his competition that rendered him the greatest rider ever in the Race Across America: His insanity.
