Why train footballers to brake?
⚽ Galiano et al.: decelerations occur up to 2.9× more often than accelerations; lower-limb muscle forces reach ~3–5× body weight. Eccentric work may improve resilience.

For gate-keeping purposes, it's common to see football tactics journalists roll out lines like "no real coaches use this type of terminology and jargon" etc etc.
So here's Francesco Farioli talking about neg-entropy, order, chaos, positional play and relationism. 🤓

Rory McIlroy shares one of his favorite mantras and mindsets.
"One of the things that I love is focusing on the process over the prize."
"I would say to myself a lot: 'Process over prize. Process over prize. Process over prize.'"
"Just to take myself away from the outcome."
Own the process and focus on what you can control.
Then he mentions what happens to all of us:
"I can get real caught up in the outcome. I just really need to remind myself that the outcome will ultimately happen if you just focus on the process. It takes care of itself."
Everyone loves outcomes, very few love the process.
It means focus, discipline, consistency, and relentless commitment.
It doesn't matter what you want, it matters what you are willing to consistently do.

Spurs are a live case study into the pitfalls of "structure-first" recruitment.
Organizational structure takes precedent over people. They're optimizing for hierarchy, not for the best possible hire. Structure doesn't make decisions, people do.
Cookie-cutter job specs are the inevitable result. By design, the odds of finding a true difference-maker (A-player) are low because the best people don't fit into boxes, which is what makes them the best people.
Football clubs can learn a lot about recruitment from tech companies. Player and staff recruitment should be people first, role second.
As a club/organization, you want to recruit the best people (A players). But A players are A players because they are unique, multi-disciplinary, and hard to define. They are not cogs in a machine. They do not fit into a predetermined cookie-cutter shape.
As a consequence, over-specifying a role filters out A players. Over-specifying a role adds (perceived) risk to hiring people who do not exactly fit the job specs. The odds of an A player emerging from the application process are low because the application process prioritizes conformity.
Teams/organizations will have gaps that need to be filled, but roles (whether player or staff) should be a rough outline, not a strict shape. Criteria should shift away from specific skillsets to scalable, context-sensitive traits - low ego, adaptable, self-motivated.
Criteria and specifications do not solve problems. People solve problems, often in ways that cannot be precisely predicted because they do so in a uniquely authentic manner.
Identify the best people/players first, build roles/processes/systems second. This principle applies to player and staff recruitment. You get better returns organizing top people/players into roles and systems that suit them rather than settling for B/C players who fit into a rigid, predefined role or system.

now imagine this on a brain where the prefrontal cortex has barely started developing, where dopamine sensitivity is an order of magnitude higher than adults, and every neural pathway is being wired from scratch in real time
thats a toddler with an ipad
giving a 2 year old short-form video is for all intents and purposes indistinguishable from giving them cocaine.
same reward pathway, same dopamine hijack, zero executive function to regulate it, and a brain that won't even finish developing before being irreparably compromised
ipad kids are brain damaged and the parents who did it to them for a "quiet dinner" (read: lazy) should be treated exactly the way we would treat anyone who gives cocaine to toddlers

Ik zoek voor morgen nog tickets voor Palmeiras - Fluminsese en ik kom niet door het ticket sales proces van Palmeiras heen. Iemand een idee, hoe ik alsnog tickets daarvoor kan fixen?

“In their book Soccernomics, FT columnist @KuperSimon and economics professor Simon Szymanski ran through several data sets on English football in an effort to quantify the importance of a manager when it comes to results. The findings were stark. On their reckoning, just 1 in 10 football managers had a statistically significant positive impact on points won.”

Do hard things. Because there’s nothing better than a hard-earned win. The pain. The struggle. The grit. And then, the reward. The feeling of knowing that you paid the cost of entry for the thing you wanted to achieve. Hard things are good for the soul.

A massive new study on peak performance included 34,000 international top performers: Nobel laureates, renowned classical music composers, Olympic champs, and the world’s best chess players. It shows early specialization is a trap, and the road to greatness is long and varied.

Een interessant artikel voor @VI_nl PRO geschreven ✍️🏼
Over hoe een v/d grootste trainerstalenten momenteel (Filipe Luís) het Z-Amerikaanse voetballandschap verovert, geïnspireerd door de ideeën van een nieuw soort voetbal: het relationisme.

In zes jaar is het aantal rijksambtenaren met 38 procent gegroeid. Ondertussen groeiden de personeelskosten van rijksambtenaren met 69 procent. Ten tijden van grote arbeidskrapte lijkt het me onverstandig dat de overheid als een dolle mensen aanneemt.
