Grok 4.5 can now build a working app from one prompt. We are going to get millions of terrible apps. But also a few great companies started by people who could never code. Sounds like a very good deal to me.
The @ycombinator Fall 2026 application deadline is today.
I was rejected twice before getting into YC with @mosaic_so.
My first two applications were over-polished and overthought. The one that worked was simple, clear, and honest.
Here’s the advice I wish I’d had earlier:
1. Co-founder quality > idea quality
Your idea may change. Your co-founder shouldn’t. YC is betting on the founders as much as the idea—ideally, people who have known and built with each other for years.
2. Tinker until the idea finds you
Great ideas often emerge from curiosity and side projects, not brainstorming sessions. Pull on interesting threads and see where they lead.
3. Build more, write less
A working demo beats application fluff. Clarity beats wordsmithing. If the idea is strong, you should be able to explain it simply.
4. Apply before you feel ready
Rejection often means “not yet.” Every application cycle forces you to sharpen what you’re building, who it’s for, and why it matters.
5. Do things that don’t scale
Scrappiness wins early. Perfection kills momentum. Let your application and founder video show how resourceful your team really is.
6. High agency creates access
We went from reading Paul Graham’s essays to speaking directly with people we admired. That happens when you show up instead of waiting to be invited.
YC gives you an environment—not a guarantee. The real work still happens afterward.
But if you’re on the fence, apply.
If you get in, your life may take a completely new trajectory. If you don’t, learn from it and keep going.
I put everything I learned—including application and interview tips—into a complete guide.
Comment “YCGUIDE” and I’ll DM it to you.
Una lección que aprendí fundando empresas: casi nunca se fracasa por falta de ideas. Se fracasa porque nadie quiere matar una idea mediocre después de haber invertido tiempo, dinero y prestigio en ella. La velocidad importa, pero saber abandonar a tiempo importa más.
🚨 Arsene Wenger on Lionel Messi's masterclass against England.
🗣️ “What Lionel Messi produced tonight is a beautiful reminder that football is not only about physical power or speed,it is first and foremost about intelligence. At 39 years old, he continues to dominate matches with qualities that do not age.
We often speak about talent, but what separates Messi from everyone else is his understanding of the game. He sees situations before they happen and makes the right decision almost every single time.
In a World Cup semi-final against one of the strongest teams in the tournament, he delivered two decisive assists and controlled the most important moments of the match. That is the mark of a truly exceptional player.
People ask how he is still performing at this level. The answer is simple: his greatest gift has always been his football brain. Physical attributes decline with age, but intelligence, vision and timing remain.
What I admire most about Messi is his simplicity. He never plays for the spectacular. He plays for what is effective, and somehow that effectiveness produces moments that nobody else in football can create.
Argentina are in another World Cup final because, when the biggest moment arrived, Lionel Messi once again made the difference. We are witnessing one of the greatest careers in sporting history, and nights like this are why football will remember him forever.”
Neymar on Messi changing the game for Argentina:
🗣️ “People will say they're surprised by what Messi did today, but for those of us who know him, this is who he has always been. Even after everything he has achieved in football, he still finds ways to amaze the world.
When the game becomes difficult and Argentina need someone to step up, Messi takes responsibility. He has this incredible ability to slow the game down, understand every moment and decide it on his own. That's something very few players in football history have ever possessed.
No matter how much pressure is on him or how hard the challenge may be, he always finds a way. That's what greatness looks like.
I've said it many times and I'll say it again,Lionel Messi is the best player I have ever seen kick a football. I was fortunate enough to play alongside him and witness his genius every single day. What people see on the pitch is only a small part of how special he truly is.
This is why he is loved so deeply in Argentina and respected all over the world. He doesn't just win matches for his country,he inspires an entire generation every time he steps onto the pitch.
Lionel Messi doesn't need to prove anything anymore, but somehow he continues to do the impossible. That's why he is Lionel Messi.”
لماذا اقول اللعب 11 لاعب ضد ميسي ظلم ؟
يا اخوان والله شيء غير منطقي.. ابدًا
هذا الملخص عبارة عن جميع لمسات ميسي منذ ان سجلت انجلترا الهدف الاول. يا اخوان ولا كرة طلعت منه بطريقة خاطئة. جميع قراراته صحيحة.
حرفيًا قلب المباراة رأسًا على عقب. https://t.co/VXCNvFZSbz
🚨Lautaro Martínez was asked about Lionel Messi’s influence during Argentina’s World Cup semi-final victory over England.
🎙️ Reporter: “Lautaro, can you tell us what Lionel Messi said to you after you came on?”
🗣️ Lautaro Martínez:
“People see the assists, the dribbles and the magic, but they don’t see what Leo does with his words.
When I came onto the pitch, he walked over to me and said, ‘Attack the space between the defenders. Go for the headers. Keep making those runs.’
I tried it the first time and it didn’t work. I looked at him, and instead of telling me to change, he kept giving me signs to keep believing. He knew the opportunity would come.
We were 1–1 with less than five minutes to play. Leo looked at the scoreboard, then looked straight at me and nodded. He didn’t even have to speak. I knew exactly what he wanted. I knew the assignment.
That’s what makes him different. He sees the game before everyone else. He knows where the space will open, and he gives you the confidence to attack it without hesitation.
Playing with him is incredible because he doesn’t only create chances with his feet. He creates belief in every player around him.
At 39 years old, he’s still leading Argentina in the biggest matches, still deciding games and still showing us why he’s the greatest footballer I’ve ever seen.
We’re in another World Cup final because once again, when Argentina needed someone to guide us, Lionel Messi was that man.”
Pep Guardiola on Lionel Messi’s masterclass against England.
🗣️ “People keep asking me how Messi is still doing this at 39 years old. My answer is simple because football has never seen anyone like him. Age defeats everyone, but somehow it refuses to defeat Lionel Messi. What he did tonight was beyond football… it was art.”
“England didn’t play against an old player. They played against the greatest mind this sport has ever produced. Two assists in a World Cup semi-final, controlling the rhythm of the biggest match on earth as if he were playing in his backyard. That is not normal. It is impossible to teach.”
“I’ve stood on the touchline and watched Leo do things that left me speechless. Tonight, sitting at home, he made me feel exactly the same. Every touch had purpose. Every pass carried danger. Every decision was perfect. He didn’t run the most but he made everyone else run for him.”
“The frightening part is that he no longer needs his young legs. His football brain is ten seconds ahead of everyone else. By the time defenders realise what is happening, the ball is already in the back of the net or a teammate is celebrating. That’s genius. Pure genius.”
“People obsess over goals, but tonight Messi reminded the world that football is about creating moments no one else can imagine. Two assists that changed a nation’s history. Two passes that carried Argentina into another World Cup final. That is the definition of greatness.”
“At 39, most legends are sitting in television studios talking about football. Messi is still writing football history. He isn’t surviving at this level he’s dominating it. That’s why I will always say there has never been, and there will never be, another player like Lionel Messi.”
“When this World Cup is over, don’t just remember the trophies or the statistics. Remember that you witnessed a 39-year-old genius walk into a World Cup semi-final against one of the strongest teams in the world… and make them look ordinary. We are watching the final chapters of the greatest football story ever written.”
🚨 Thomas Tuchel on Lionel Messi's masterclass against England.
🗣️ “We prepared for Lionel Messi in every possible way. We spoke about him before the game, showed clips, worked on our positioning and our pressing triggers. But some players simply cannot be prepared for completely, and Messi is one of them.
You can control him for long periods, and then in one moment he changes the entire match. That is exactly what he did tonight.
His two assists were not about luck or individual brilliance alone,they came from his understanding of the game. He sees spaces before anyone else does and has the calmness to make the right decision under enormous pressure.
What impresses me most is that at 39 years old, he doesn't rely on physical attributes. He controls the rhythm of the game with his intelligence, his timing and his ability to make everyone around him better.
England defended well for large parts of the match, but against players like Messi, one small mistake is enough. He doesn't need ten opportunities,he only needs one.
It is a difficult defeat to accept because we knew exactly what he was capable of, yet we still couldn't stop him when it mattered most.
Two assists in a World Cup semi-final and another World Cup final for Argentina. We are talking about one of the greatest players football has ever seen, and tonight he reminded the world why.”
Pep Guardiola on Spain taking a 2–0 lead over France in the FIFA World Cup semi-final.
🗣️ “This is the Spain I want the world to see. Brave, intelligent and fearless. They’re not just beating France,they’re controlling them, suffocating them and making one of the strongest teams in the world look completely lost.”
“People said this young Spain side wouldn’t be ready for a World Cup semi-final. Look at them now. Every pass has purpose, every movement creates space and every player understands exactly what the team needs.”
“France came with world-class players, but Spain have shown that football intelligence, courage and teamwork can make even the biggest stars look ordinary. This has been a football lesson.”
“The way Spain have dominated possession, pressed relentlessly and punished every mistake has been exceptional. They aren’t relying on luck,they’re earning every single moment through superior football.”
“At 2–0, this isn’t just a scoreline,it’s a statement to the rest of the world. If Spain continue playing with this confidence and quality, they’ll be the team everyone fears. This is football at the highest level.”
🚨 Zlatan Ibrahimović respondió con dureza a las declaraciones de Hossam Hassan, quien insinuó que Argentina fue favorecida por el marketing del Mundial.
🗣️ “Cada vez que Messi gana, aparecen las teorías de conspiración. Es la misma historia de siempre. En lugar de aceptar la derrota, buscan excusas.
Si vas ganando 2-0 y aun así no eres capaz de ganar el partido, no culpes al marketing, a los árbitros ni al torneo. Primero mírate al espejo.
No respeto ese tipo de excusas. Un seleccionador nacional debe asumir la responsabilidad y dar la cara, no inventar narrativas para desviar la atención de lo que ocurrió en la cancha.
Argentina luchó hasta el último minuto y se ganó su clasificación. Si pierdes, acéptalo, aprende de ello y vuelve más fuerte. De eso se trata el fútbol.”
Lionel Messi is having yet another exceptional World Cup, reminding us every game what greatness looks like. But I'm more interested in the kind of man he is, and why he's an outstanding role model for young men, both on and off the pitch.
At 39 years old, the man is still lighting up th World Cup. He moves with that same magic he had as a teenager, and doing it all with relentless drive and consistency. Year after year, decade after decade, he shows up prepared, humble, and fully committed. No drama, no excuses, just elite standards meticulously maintained while the world watches.
His character shines brightest off the ball too. Messi’s loyalty to his teammates is legendary - celebrating their goals as passionately as his own, lifting the squad in big moments, and building genuine bonds that last across clubs and national teams. He leads by making others better, not by demanding the spotlight.
And then there’s his dedication to his family. Watch him point to the sky after a goal (honouring his late grandmother who first put him on the pitch), kiss his wedding ring for his wife Antonela (they've been together since their teenage years), or see him light up surrounded by his three sons - Thiago, Mateo, and Ciro - on the field or in the stands. Whether it’s sharing a trophy moment or simply being present, Messi’s love for his family is always front and center.
He lives the balance: world-class drive on the pitch, devoted husband and father off it.
That’s the kind of gentleman we can all learn from. True character isn’t alpha male loud dominance - it’s consistency in your craft, fierce loyalty to your people, and making family the real priority that fuels everything else. It’s building a legacy that matters long after the final whistle.
Messi shows us the power of showing up every day - for your work, your team, and the ones you love most.
So gentlemen, unleash the Messi in you, and build your legacy. Cheers 🥂
Mohamed Salah on Lionel Messi’s performance against Egypt:
🗣️ “Lionel Messi showed tonight why so many people consider him one of the greatest players in football history. Every time he received the ball, you could feel that something dangerous was about to happen. His vision, composure, and ability to control the rhythm of the match were on another level.”
“We tried everything to limit his influence, but players like Messi only need one or two moments to change a game. He punished every small mistake, created chances out of nothing, and gave Argentina the belief they needed in the biggest moments.”
“As opponents, you want to stop him, but as footballers, you also have to appreciate what you’re witnessing. He was the difference tonight. He led his team with experience, intelligence, and incredible quality when the pressure was at its highest.”
“Of course we’re disappointed with the result because we believed we could go through, but I have nothing but respect for Messi’s performance. He proved once again why he has achieved everything he has in this game.”
Hoy hace exactamente 3 meses que volví a Argentina. Y necesito contarles la historia completa. 🇦🇷❤️
Tengo 26 años. El año pasado vine por primera vez — con un pasaje de vuelta para 7 días.
Me quedé 3 meses. Algo en esta tierra me atrapó desde el primer día con una fuerza que no supe explicar entonces y que todavía me cuesta explicar hoy.
Volví a Portugal. Pensé que con el tiempo se me iba a pasar. Que era simplemente el efecto de un viaje largo, de una experiencia intensa.
No se me pasó.
Pasé 5 meses en Europa con una nostalgia de Argentina que no sabía que era posible sentir por un país que ni siquiera era el mío.
Un dolor silencioso, constante, que aparecía en los momentos más inesperados — viendo una foto, escuchando música, pensando en las calles de Buenos Aires, en el fin del mundo en Ushuaia, en esta tierra que me cambió sin pedirme permiso.
Y volví. Hace exactamente 3 meses. Y acá estoy.
Viajé por más de 40 países. Pero ningún lugar — ninguno — me hizo sentir lo que siento aquí.
Cuando miro la bandera celeste y blanca algo se mueve dentro de mí que no puedo controlar. Una sonrisa que sale sola. Los ojos que se humedecen sin permiso.
Como si una parte de mí reconociera esta tierra como propia — aunque no haya nacido aquí.
No me siento extranjero. Nunca me sentí extranjero en Argentina.
Soy portugués. Con todo el orgullo del mundo. Pero hay una parte de mí que ya es argentina — y esa parte no va a ningún lado nunca más. 🙏
No todo el mundo tiene la suerte de encontrar un segundo hogar. Yo lo encontré. Y se llama Argentina. ❤️🇦🇷
¡VIVA ARGENTINA! 🦁⚡️🇦🇷🇵🇹

VER A MESSI LLORANDO.
Llorando de emoción. Llorando como aquel chico que un día soñó vestir la camiseta de la selección argentina.
Viéndolo, uno comprende que la verdadera grandeza no está solo en los títulos. No está únicamente en haber ganado un Mundial, las Copas América, la Finalissima, los Balones de Oro o en haber batido todos los récords imaginables.
La verdadera grandeza está en que, después de haber alcanzado todo, todavía sea capaz de emocionarse hasta las lágrimas.
Lágrimas que no nacen del éxito. Que nacen del amor.
Amor por la camiseta. Amor por sus compañeros. Amor por un pueblo que lo acompañó en tantos momentos difíciles y hoy lo abraza como el héroe que siempre fue.
Y una imagen conmueve todavía más: la devoción con la que lo rodea el grupo. Cada abrazo, cada mirada y cada gesto reflejan algo que trasciende el fútbol. Sus compañeros no solo juegan con él; juegan por él y para él. Quieren verlo feliz. Quieren regalarle una nueva alegría al capitán que durante tantos años cargó sobre sus hombros la presión y el peso de un país entero.
Eso no se impone. No se compra. No se fabrica.
Se gana con humildad, con ejemplo, con sacrificio y con una vida dedicada a representar a la Argentina con orgullo.
Por eso, ver a Messi llorando no es una muestra de debilidad. Es la prueba más hermosa de que, incluso en la cima del mundo, aún conserva el corazón intacto.
Y quizás por eso millones de argentinos no vemos solamente al mejor futbolista de todos los tiempos.
Vemos al hombre que nunca abandonó su niño interior. Al hombre simple. Al ser humano.
"Al que nos llena de orgullo".

Un tercio de gol es de Enzo, golazo.
Otro tercio es de Lautaro, gran centro.
Y otro tercio es de Nico González, que mete un pique larguísimo y "distrae" al central, que no termina de cerrar a Enzo para el gol.
Estas cámaras se deberían mostrar mucho más.
Nadie habla de la humildad de la selección Argentina
Enzo Fernández vale 100 millones de euros y tiene el gesto de frenar y darle la exclusiva a un periodista con discapacidad.
Además le da un mensaje de esperanza nombrando a Dios.
Sos INMENZO, Enzo
