Norway wins the most medals at the Winter Olympics, with a population of just 5.6 million. People say it’s because Norway is a winter wonderland, but they’re also elite at triathlon, beach volleyball, cycling, and as the world is now seeing, soccer.

A big part of their success is how they treat youth sports—and it’s the opposite of what we do in the US and Canada. Here’s what we can learn from Norway:

1. Scorekeeping:

In the US: Youth sports tend to be hyper competitive even at early ages. Leagues almost always keep score.

In Norway: Scorekeeping isn’t even allowed until age 13.

Removing winners and losers keeps the focus on the process not outcomes. It keeps kids engaged longer because it minimizes pressure (and tears) and maximizes fun, learning, and growth. The goal isn’t to win a third grade championship. It’s to love sport and keep playing.

2. Trophies:

In the US: If you give everyone a trophy, you’re creating snowflakes who will never gain a competitive edge.

In Norway: Whenever trophies are awarded, they are handed out to everyone.

If getting a trophy makes young kids feel good, we should give them trophies. Maybe they’ll come back and play again next year!!

As for the creation of snowflakes with no competitive edge—Norway’s athletes are tough as nails and all they do is win.

3. Prioritizing Fun:

In the US: Far too often, the goal is to win.

In Norway: The national philosophy is “joy of sport.”

Youth sports in the US are driven by adults, ego, and money. Youth sports in Norway are driven by fun.

Only half of kids in the US participate in sports. The number one reason they drop out: because they aren’t having fun anymore. In Norway, 93% of kids participate in youth sports. Fun is the foremost goal.

4. Playing Multiple Sports:

In the US: There’s pressure to specialize early and play your best sport year round.

In Norway: Try as many sports as you can before specializing as late as college.

Norway encourages kids to try all types of sport. This reduces injury and burnout and increases all-around athleticism. It also helps promotes match quality, or finding the sport you are best suited for as your body develops, which is impossible if you commit to a single sport too early.

5. Affordability

In the US: There is increasingly a pay-to-play model with high fees for leagues, equipment, and travel. This excludes many kids from playing.

In Norway: It’s a national priority to keep youth sports affordable and therefore accessible for all.

Kids aren’t priced out, which creates opportunities for everyone to participate (and develop into athletes), regardless of their parents’ income level.

Norway’s sporting success isn’t just speculation or a nice story. A large body of research supports their approach:

• Studies show athletes who specialize later in life have a significantly higher chance of becoming elite.
• Soccer players whose motivation is primarily internal (versus external) have more than a 3x better chance of making it to an elite level.
• The number one predictor of whether or not kids stay in sport is are they having fun.
• Parents connect winning to having fun whereas kids say having fun is about being with their friends and learning.

We could learn a lot from Norway:

In the US, 70% of kids drop out of youth sports by age 13. This not only diminishes an elite-athlete pipeline, but it also destroys an opportunity for healthy habits and all the character lessons kids can learn from sport.

In Norway, lifelong participation in sport is the norm. The goal isn’t to have the best 9U team. It’s to develop the best athletes. Those are two very different things. And Norway has the medals to prove it.

[Sosa | Mental Strategist @MetaMorpehus]

Avoidance creates anticipatory dread as you always wait to see if you act or not, psychologically this is a form of catastrophising.

Stuck in the future by feeling unsettled in the present.

Which naturally takes away from the enjoyment of what you can see in front of you.

Once again, this weighs heavy on the soul because we all know how quickly time moves, seasons change, children grow and whilst you understand this fact you are still stuck in this constant apprehension.

Guilt only reinforces this avoidance cycle because you begin to feel ashamed that you struggle to experience gratitude when you look in the eyes of those you love.

Please know you are not broken or evil, and the fact you can observe this proves that you are not.

Instead you must confront what you hide from within yourself and life. Those decisions you've put aside for a long time, the ones that you're thinking of right now.

As a matter of fact, these are the root of prolonged stress and anxiety.

Then, invest in yourself.

The more you invest whether in money, time, or energy the more you show the subconscious that you are worthy of the result.

In other words, your unconscious mind speaks literally. If you invest in you, it proves you are worthy of it.

The opposite is also true.

Highly important you learn to love the sweet sensation of stress, train your nervous system to relax in panic.

Dr Claire Weekes’ floating technique is ridiculously effective here, alongside general body-awareness practice: qi gong, meditation but only when practised in the stressful moment.

Because every time you avoid instead, you validate the imaginary scenario fear invented and every time you stay, you teach it the scenario was never real.

Thirdly, think of the bigger picture.

What example do you genuinely want to set for your children?

Picture they watch your every action because they do, and this is what they’ll deeply remember for the rest of their lives.

Which allows you to self-actualise.

As you prioritise joy, passion, and the bigger purpose which unlocks gratitude and excitement in you, then fear loses all its power because you move toward what you want, instead of clinging on to keep what you already have.

Each morning as you wake up hold the image of the above in your mind. Let it motivate you. Let it steer you toward inspiration.

As a result this rewires the association to fear.

So from now on, every time you feel the urge to flee, you are naturally reminded it’s an opportunity to create more success, more confidence, more growth.

Little by little, and eventually fear reassociates entirely and it becomes an anchor of pleasure.

Tu cuerpo escucha la historia que le cuentas. “Ya estoy envejeciendo”. “Cada vez tengo menos energía”. “Mis mejores años ya pasaron”. Muchas personas empiezan a ensayar su deterioro mucho antes de que llegue. Ten cuidado con lo que tu mente le enseña a tu cuerpo a creer.

[Unfiltered @quotesdaily100]

HUMAN NATURE:

1. People rarely get angry at the truth. They get angry because the truth arrived at the wrong moment.
2. Give a person too many options and they choose nothing. Give them two, and they decide fast. Freedom of choice is often the enemy of action.
3. Most people don't want advice. They want someone to agree with the decision they've already made.
4. When someone shows you who they are in a moment of anger, believe that version. Not the apology that follows.
5. Everyone thinks they are the exception to the rule. That belief is the rule.
6. People forgive others not because they deserve it, but because carrying the weight of resentment becomes too expensive.
7. Most people fear being alone far more than they fear being with the wrong person. That fear fills the world with bad relationships.
8. Humans are the only species that will accept suffering today in exchange for a promise about tomorrow. That promise is often never kept.
9. The version of you that people defend in your absence tells you more about them than anything they say to your face.

There's a kind of tiredness that never goes away. It's the tiredness of spending years being someone we're not. Always adjusting. Always performing. Laughing at things you don’t find funny. Saying yes when your soul says no. Chasing things you never wanted. Slowly abandoning little pieces of yourself just to be accepted. But maybe you don’t need a completely new life. Sometimes you just need to return to yourself. Your real, honest self.

[Epsiba Psicología @psicoepsiba]

Retomar algo que antes te gustaba cuando el ánimo está bajo o hay una depresión es uno de los consejos más repetidos. Y tiene sentido en teoría. El problema llega cuando lo intentas y no funciona: vas a dar un paseo, quedas con alguien, pones una serie... y no sientes nada especial. Y de ahí a "estoy peor de lo que pensaba" hay muy poco camino.

En un estado de ánimo normal, primero tienes ganas y luego actúas. Cuando el ánimo está bajo durante un tiempo prolongado, ese orden se invierte: la motivación llega después de actuar, no antes.

Si mides el resultado justo en el momento de hacerlo, estás usando la regla equivocada. La ausencia de disfrute inmediato no dice que estés peor. Solo dice que el sistema todavía está arrancando, pero empezar ya es un buen indicador de cambio.

Marco Aurelio dejó una observación que sigue siendo difícil de ignorar:

"Siempre que otro te vitupere, odie o profiera palabras semejantes, penetra en sus pobres almas, adéntrate en ellas y observa qué clase de gente son. Verás que no hay necesidad de atormentarte pensando en la opinión que tengan de ti".

Si la IA ya hace el %80 del trabajo, ¿qué te toca hacer a vos?

Anthropic se metió a mirar 400.000 sesiones reales con Claude Code (su IA que no solo te contesta, sino que se mete en tu computadora y ejecuta) y el 77% de las veces la persona terminaba con algo impecable, que parecía listo. Pero, cuando fueron al detalle, a verificar si eso de verdad andaba, el número se derrumbó al 15%.

¿Qué pasaba en el medio? La herramienta era la misma para todos, así que la diferencia tenía que estar en otro lado: en quién la usaba. Los que conocían en profundidad el tema del que se trataban las tareas eran casi los únicos que lograban un proyecto realmente en condiciones. Los otros caían en el engaño.

Lo que encontraron es que vos tomás el 70% de las decisiones de qué hacer y la IA el 80% sobre cómo hacerlo. Estamos dejando de ejecutar para dirigir y la expertiz en el área de una tarea es nuestro mayor superpoder.

Por eso, un contador, abogado, financiero, etc. que jamás escribió una línea de código, pero que conoce su tema al detalle, le saca a la IA mucho más jugo del que parece. Su reemplazo está mucho más lejos de lo que se ve a simple vista.

Cuanto más rema la IA, más sube el valor de saber para dónde ir.

El cómo ya lo resuelve la máquina sola. El hacia dónde, todavía lo ponés vos.

Your brain runs a threat alarm, and sleep is what keeps it quiet. Berkeley researchers took one night of sleep from healthy people, put them in a brain scanner, and showed them disturbing images. Their amygdala, the brain's fear center, fired 60 percent harder than in people who had slept.

The scientist who ran it, Matthew Walker, said the size of that jump surprised them. The reason is simple. When you are rested, the prefrontal cortex, the calm planning part of your brain right behind your forehead, holds the amygdala on a leash. Take sleep away and the leash drops.

That was one night in a scanner. The longer test came in 2017, when Oxford put 3,755 students through an online course that teaches the brain to sleep better, then tracked their mental health. Better sleep cut insomnia sharply, and it also brought down anxiety, depression, and even paranoia. The better sleep was what drove the rest. Fix the sleep first, and the other problems eased.

Food went through the same kind of trial. In the SMILES study, 67 adults with moderate to severe depression were split in two. One group worked with a dietitian and moved to a Mediterranean style diet, heavy on vegetables, fish, nuts, and olive oil. The other group just got friendly visits on the same schedule. Twelve weeks later, 32 percent of the diet group had improved enough to no longer count as depressed, compared with 8 percent of the other group. Change the food, and about one in four extra people pulled out of it. That trial was small and bigger reviews show a smaller effect, but the direction has held.

Then movement. A 2024 review in the BMJ combined 218 trials covering 14,170 people with depression. Walking or jogging produced a solid drop in symptoms, landing in the same range as talk therapy and antidepressant pills. The gym is optional. A separate 2024 analysis of 96,173 adults found that each extra 1,000 steps a day was linked to about 9 percent lower odds of depression, and people near 7,000 steps a day had about 31 percent lower risk than people who barely moved.

So the walk to the further pickup point, the proper lunch instead of coffee and willpower, the early night you keep trading away. Each one has been measured in a controlled trial, and each one moves the same score doctors use to measure depression.

YOU ARE THINKING TOO MUCH

Nobody cares. You can just do things. Most things do not matter. Everyone has their own problems. Go after what you want. Do not miss opportunities. Make your life revolve around your goals. Ask without hesitation. Be cringe. Live freely. Sleep without thinking about the past. Every day could be your last. Do whatever it takes to fulfill your purpose.

When you understand that everyone has their own worries, you stop thinking about how others perceive you.

If you do not act as the main character of your own life, it means you are placing others above yourself.

Then you never truly lived.

Major cheat code for life: Become difficult to rush. The world will pressure you to rush into everything. Rushed decisions. Rushed conversations. Rushed relationships. Rushed timelines. There's immense power in rejecting that trend. Slow down. Create space to think clearly.

To reduce your stress, try not to have strong and loud opinions about everything.

Smart people are selectively ignorant about most things, and focused on some things.

You don’t need to be a tech bro to buy a good laptop.👇

Most sellers will throw around big grammar like:
Core i7, 13th Gen, SSD, NVMe, GPU, VRAM…
and confuse you into overspending.

Simple breakdown:

• Core i3 / i5 / i7 = Laptop power level
i3 = basic use
i5 = best for most people
i7 = heavy work like editing/gaming

But here’s the real trick…

Generation matters more than i3/i5/i7.

A 13th Gen i5 can be faster than an old 7th Gen i7.

Read that again.

That “cheap Core i7 laptop” some sellers hype?
It may actually be old, slow, and a bad deal.

Then storage:

• HDD = very slow
• SSD = fast
• NVMe SSD = lightning fast

Rule of thumb:
Never buy a laptop with HDD in 2026 unless you enjoy suffering.

Bonus Windows hacks many people don’t know:

• Win + V → See everything you copied today
• Win + Ctrl + L → Live captions for videos/audio
• powercfg /batteryreport → Check real battery health

Bottom line:
Stop buying laptops because of sweet mouth marketing.

A modern Core i5 + recent generation + NVMe SSD will serve most people better than an ancient “Core i7.”

Laptop sellers won’t tell you this.
Now you know😁

I’m increasingly convinced that the ultimate sign of growth is faster recovery. You still get upset. You still make mistakes. You still have bad days. But you return to center faster. Apologize faster. Reset faster. Learn faster. Fast recovery compounds.

[Adam Shuaib @adamshuaib]

Most ultra successful people have a very low need for social approval, although society tends to label this incorrectly as a red flag.

The average person is terrified of looking like a fool or bothering people. I’ve met CEOs that will send ten follow-up emails to a dream hire or pitch their idea to a stranger in an elevator without a second thought. This personality type means they can bypass the politeness instinct that slows down everyone else’s career.

Hesitation to ask for help or feedback is a common bottleneck in most professions; someone who isn't slowed by the fear of being annoying can squeeze a year’s worth of progress into a week.

There are very few things in life that shameless persistence won’t give you.

Business Lessons I wish someone had told me at the beginning

1. Sell what is selling, not what you want to sell
2. Charge high - rich clients act and pay better
3. Never do discounts on your service
4. Never work for free (testimonial if new)
5. Ignore unsuccesful friends and family
6. Hire talented people, the chance of you fixing a loser with a sob story is highly unlikely
7. If one potential client can't afford your service, the next one will, the world is full of abundance
8. Scarcity mindset will cage your income potential
9. Copy people that have made it, your ideas probably suck, just copy what works
10. The bar is 30 feet lower than what you think it is, the bar is way lower in reality than in your mind
11. Most people suck at what they do and still get paid 12. Saturation is a myth
13. Find a niche where dumb people are getting rich
14. Choose the simple money witb low risk
15. Cash flow over evertything
16. Ignore criticisms over your business niche, no matter what niche it is people will mock it somehow, just follow the money
17. You don't get ready by "getting ready" you get ready by doing

No needle is going into that arm. That metal gun is firing a hair-thin jet of vaccine straight through the skin, and they used it on sleeping babies without waking them.

It's a jet injector. A spring-loaded piston shoves a measured dose through an opening about 0.005 inches wide at enough pressure to push liquid past the outer layers of skin in under a tenth of a second. The dose goes in, the arm barely registers it, the operator moves to the next person in line.

The model in this clip ran on a foot pedal. Aaron Ismach designed it that way so it would work in villages with no electricity. One vaccinator could clear close to 1,000 people an hour, and the reservoir held 500-plus doses between refills.

This is the tool that helped wipe out a disease. 1967 was the official start of the WHO smallpox campaign. In West Africa alone, these guns delivered 92 million smallpox doses and 15 million measles doses between 1967 and 1969. Nicaraguans called it la pistola de la paz. The peace gun.

Then it disappeared, and the reason is the one detail the video doesn't show. The same nozzle touched every arm in line. Fire it against freshly broken skin a thousand times an hour and you are quietly moving fluid between strangers. Years later a single jet injector at a Los Angeles clinic seeded a hepatitis B outbreak across dozens of patients from that one shared nozzle.

The feature that let one person vaccinate a whole village is the feature that got it pulled. It was replaced by a forked needle you could boil and reuse, that sipped a quarter of the vaccine and only ever touched one arm at a time. The fastest vaccination tool ever built lost to a sharpened scrap of wire.

Ten lazy years can disappear the moment you lock in. Six months of discipline can erase a decade of drifting. Momentum is magic. It turns yesterday's failures into tomorrow's fuel.
