Why 'All In' Is No Recipe for Success


"A single-minded, relentless drive -- that's what it takes to be successful. Be "all in." Burn the boats behind us.

That message is ingrained in our society, from self-help books to Nike advertisements to social media influencers all telling us that we need to commit more and strive harder. The world continually sends the signal to narrowly define your goals and objectives and chase them with an obsessive zeal.

For much of my life, I believed in this credo. I was a phenom of an athlete, becoming the fastest high-school miler in the country my senior year, when I ran a 4:01 mile. In the midst of my ascent, writing in my high school running log, I left a comment with the typical self-dramatizing flair of a teenager: "I don't go out, I don't party, I don't live the life of a normal teen. Is this even living? Why do it? I want to be the best. I will not settle for mediocrity. I will take my body through hell, testing its limits."

Teenage Steve was certainly obsessive, and he was convinced that going all in was the key to success. He was mostly wrong.

When my progress as a runner stalled, I spent time with a renowned sports psychologist. He told me a story about a world-class runner who had become stuck while struggling to make the transition from success in high school and college to Olympic-level performance. The psychologist asked me, "Do you want to know what helped her break through?"

I leaned forward, prepared to hear what surely was the secret to making the Olympics. He looked me in the eyes and replied, "knitting."

She had taken up knitting to relax and to take her mind off running. I was too young and stubborn to heed the advice. I doubled down -- and never ran faster than my high-school record or broke a 4-minute mile.

In the years since, working as a coach with elite performers, including Olympic medalist runners, I kept noticing that their single-minded focus -- their supposed superpower -- was getting in their way. Their focus on achieving specific goals had become an obstacle, a constant, disabling signal that they were not measuring up. The relentless approach was backfiring.

Research backs this up. According to a 15-year survey of more than 5,000 would-be entrepreneurs, those who kept their day jobs, instead of focusing only on their own project, were 33% less likely to fail.

Researchers at Michigan State University looked at over 100 years of Nobel Prize-winning scientists and found that they were more likely than their less-accomplished peers to have creative interests outside of their research. The prize-winners were 22 times more likely to perform, sing or act as a hobby; 12 times more likely to pursue creative writing; and about seven times more likely to participate in a craft like sculpting, painting or glassblowing.

As for athletes, those who specialize early in one sport tend to be worse off over the long haul than their compatriots who dabbled in other activities and specialized later. A 2021 meta-analysis evaluating 6,000 athletes found that those who made it to world-class competition tended to have more multisport practice, started their primary sport later, accumulated less practice time and progressed a bit more slowly.

To be sure: The more we care, and the more our job or pursuit feels like a part of who we are, the harder we'll work. That's helpful to a certain point. Research looking at everything from getting people to vote to taking care of the environment to eating healthier tells us that when we identify closely with something, we're more likely to make sure our actions and identity align.

But such narrowing comes with a downside. As we shed other parts of ourselves, and that one activity becomes an ever bigger presence, fear starts to take over. We don't just want to succeed. We have to. We're not just playing a game -- it's our self on the line. Fear of failure rises and moves from "I failed" to "I am a failure."

Studies by Patrick Gaudeau and colleagues at the University of Ottawa found that striving with a hyper-results-oriented approach leads to less experimentation and a propensity to stick to the status quo and avoid challenges.

In sports, such striving is at the heart of choking and underperformance. Athletes with a singular identity based on their sport more often experience what's called threat-stress response. When fear of failure dominates, athletes produce more of the stress hormone cortisol and less testosterone, a mixture that nudges us toward avoidance and protection. When we feel challenged but not threatened, it's the opposite effect: more testosterone, less cortisol.

When outcomes are all that matter, and winning or losing becomes self-defining, our default response isn't to become a warrior. It's to retreat.

The secret is to go in a different direction. When the world screams to go narrow, elite performers learn to go broad.

It's a lesson that professional mountain-biker Kate Courtney had to learn.

As she told me, "My superpower is being able to grind." And it worked for a while. But after initial success, in the prime of her athletic career at the age of 25, she felt worn out, and her performance was going backward. Courtney didn't do what most athletes do in those moments: double down and work harder. She eased up.

"When you have a more well-rounded life, it doesn't take away, it doesn't distract you as an athlete," she said. "It makes you stronger and better. And able to have a clear head when you get the opportunity to line up . . . I bring who I am to the bike. But the bike does not make me who I am." Now 29, Courtney is currently ranked ninth in the world.

It's not that knitting is special, any more than the various hobbies that the Nobel-winning scientists took up. But any activities or perspectives that give complexity to our self-image help send a message to our brain that the thing in front of us is important, but it's not all that matters.

Other performers I surveyed spoke of simply putting the experience above the outcome. As one world-class runner put it, "I had to know when to throw the watch away." An entrepreneur relayed to me, "Somewhere along the way, we numb ourselves to the experience in the name of chasing metrics."

It's better, he said, to remember what the motivation was for the enterprise in the first place: "It's the feeling, the excitement, curiosity, just this energy that makes us feel alive."

Ar švinas sumažino senovės romėnų IQ?


 „Senovės Romoje švino tarša buvo tokia didelė, kad gyventojų intelekto koeficientas sumažėjo maždaug trimis ar daugiau taškų.

 

 Elitai buvo veikiami švinu per vandens vamzdžius, puodus, kosmetiką ir sirupus, kurie saldino jų vyną. Tačiau labiausiai paplitęs romėnų poveikis buvo pramoninė tarša, kurią sukėlė metalų, naudojamų pinigų uždirbimui, kasyba ir lydymas.

 

 Romėnai lydydavo galeną – rūdą, kurioje gausu švino, kad išgautų monetoms reikalingą sidabrą. Švinas buvo pagrindinis proceso šalutinis produktas.

 

 "Už kiekvieną sidabro unciją, kurią pagaminate, galite pagaminti tūkstančius uncijų švino, - sakė klimato ir aplinkos mokslininkas Josephas McConnellas iš Reno (Nev) dykumų tyrimų instituto. - Niekas negalėjo to išvengti.”

 

 McConnell ir jo kolegos įvertino romėnų švino poveikį ir pranešė apie apytikslį IQ kritimą, kurį epidemiologai siejo su tokiu poveikio lygiu. Išvados buvo paskelbtos praėjusį mėnesį Nacionalinės mokslų akademijos darbuose.

 

 Tyrėjai ištyrė oru sklindantį šviną, kuris dreifavo į šiaurę nuo senovės Romos ir buvo išsaugotas iš Grenlandijos ir Rusijos Arkties išgautų ledo šerdžių. Pavyzdžiai, datuojami prieš 2500–1400 metų – epochą, kuri apėmė Romos imperijos iškilimą ir žlugimą.

 

 McConnell sakė, kad komanda sugebėjo suderinti šerdyje rastus cheminius švino pirštų atspaudus su švino šaltinių izotopais, išgaunamais imperijoje, o atmosferos modeliavimas taip pat parodė švino dreifą. Darbas atskleidė, kad švino taršos piką pasiekė Pax Romana, klestėjimo laikotarpis, kai senovės Roma apėmė Artimųjų Rytų, Europos ir Šiaurės Afrikos dalis.

 

 Tyrėjų modeliai parodė, kad tuo metu kasmet buvo išmetama nuo 3300 tonų iki 4600 tonų švino, o tai rodo, kad senovės romėnuose švino lygis buvo nuo 2 mikrogramų iki 5 mikrogramų viename decilitre kraujo. Kiti tyrimai rodo, kad IQ sumažėjo maždaug 3 taškais.

 

 Palyginimui, tuo metu, kai 1970 m. buvo priimtas Švaraus oro įstatymas, reglamentuojantis švino ir kitų oro teršalų kiekį JAV, pagal Britų Kolumbijos Simono Fraserio universiteto sveikatos mokslų profesoriaus Bruce'o Lanphearo teigimu, amerikiečių vaikai vidutiniškai turėjo apie 15 mikrogramų švino viename decilitre kraujo, o intelekto koeficientas sumažėjo septyniais taškais.

 

Jis tyrime nedalyvavo.

 

 Jis sakė, kad švino poveikis yra susijęs su mirtingumo, priešlaikinio gimdymo ir anemijos padidėjimu, taip pat sumažėjusiu kognityviniu funkcionavimu. Vaikams, kurie yra labiau pažeidžiami, švinas siejamas su IQ kritimu, kuris išlieka, laikui bėgant.

 

 Lanphear teigė, kad naujajame tyrime, greičiausiai, nepakankamai įvertinamas, romėnus užklupęs, poveikis, tačiau švino paplitimas pabrėžia populiarią teoriją, kad teršalas galėjo turėti įtakos imperijos nuosmukiui.

 

 „Tai suteikia daugiau svarbos idėjai, kad švinas buvo vienas iš daugelio rizikos veiksnių, kurie galėjo prisidėti“, – sakė jis. „Žinoma, būtų sunku pasakyti, kiek tai konkrečiai turėjo įtakos“.” [1]

Did Lead Lower The IQs of Ancient Romans?


"Lead pollution in ancient Rome was so high that it dropped the population's IQ by around three points or more.

Elites were exposed to lead through water pipes, cooking pots, cosmetics and the syrups that sweetened their wine. But the most widespread exposure for Romans came from industrial pollution caused by the mining and smelting of metals used to make money.

Romans melted down galena, a lead-rich ore, to extract the silver needed for coins. Lead was a major byproduct of the process.

"For every ounce of silver you produce, you might produce thousands of ounces of lead," said Joseph McConnell, a climate and environmental scientist at the Desert Research Institute in Reno, Nev. "Nobody could escape it."

McConnell and his colleagues estimated the Romans' lead exposure and reported the rough drop in IQ that epidemiologists have associated with that level of exposure. The findings were published last month in the Proceedings of the National Academy of Sciences,

The researchers examined airborne lead that drifted north from ancient Rome and was preserved in ice cores extracted from Greenland and the Russian Arctic. The samples dated between 2,500 and 1,400 years ago -- an era that included the Roman Empire's rise and fall.

The team was able to match the chemical fingerprints of lead found in the cores to the isotopes of lead sources mined within the empire, McConnell said, and atmospheric modeling also showed the lead's drift. The work revealed that lead pollution peaked during the Pax Romana, a prosperous period when ancient Rome spanned portions of the Middle East, Europe and North Africa.

The researchers' models showed 3,300 tons to 4,600 tons of lead were emitted annually at the time, suggesting that ancient Romans had lead levels between 2 micrograms and 5 micrograms per deciliter of blood. Other research links that amount to a decline of around 3 IQ points.

In comparison, at the time the Clean Air Act of 1970 was passed to regulate lead and other airborne pollutants in the U.S., American children averaged about 15 micrograms of lead per deciliter of blood with an associated seven-point drop in IQ, according to Bruce Lanphear, a professor of health sciences at Simon Fraser University in British Columbia. He wasn't involved in the study.

Lead exposure is associated with increases in mortality, preterm births and anemia as well as reduced cognitive functioning, he said. For children, who are more vulnerable, lead is associated with IQ drops that persist over time.

Lanphear said the new study likely underestimates the amount of exposure that beleaguered the Romans, but the pervasiveness of lead underscores a popular theory that the pollutant might have played a role in the empire's decline.

"It gives more weight to the idea that lead was one of many risk factors that could have contributed," he said. "How consequential it was, of course, would be difficult to say."" [1]
