Elon Musk fired 80% of Twitter (6500 people) and everyone thought that Twitter was doomed. He was right. Everyone was wrong. It’s the management masterclass of the decade and every entrepreneur must understand why it worked 🧵:

Startups used to need armies. Now it’s:. • 3 maniacs.• 1  weird idea.• 10 AI tools. = a company that scares the incumbents.

AI has no feelings. No bias. No ego. But you do. And that’s your edge — if you can control it. Be human on purpose.

Startup death = death by busywork. Slack ≠ momentum. Meetings ≠ clarity. Productivity ≠ progress. Ship. Sell. Repeat.

Forget MVPs. Ship Minimum Magical Products. Delight > Features. Nobody shares “meh.”.

Longevity isn’t just biohacking. It’s anti-fragility. Strong legs, good sleep, a mission, and friends that lift heavy things. Live long enough to outbuild everyone.

The next billionaires will look broke for a while. 1 person. AI stack. Niche cult. Zero clout. Then boom — empire.

B2B SaaS = spreadsheet with a login. AI doesn’t need that middle layer. The winners will feel like magic, not admin panels.

You’re not too late for AI. You’re just too lazy to play. Write 50 prompts. Break 5 tools. Ship 1 thing. Repeat until dangerous.

Your real competition isn’t other founders. It’s distractions. Slack. Email. Anxiety. Out-execute by out-focusing. Kill your tabs before they kill your output.

Remote isn’t the revolution. Asynchronous is. If your company still lives in meetings, it’s already dying in slow motion.

The secret to scaling?. Say “no” like a sociopath. Not maybe. Not later. Just: “No.”. Then go build.

Notifications are taxes. Slack is a casino. Meetings are emotional debt. Control your environment, or it controls your outcomes.

The best ideas look like bad jokes to VCs at first. Then they hit $100M and everyone says “I always believed.”. You didn’t. You thought it was dumb. Stay weird.

Don’t hire for experience. Hire for curiosity + violence. A mildly unhinged person with taste and a deadline will outperform most corporate vets.

Your resume is cute. But have you shipped anything lately?. Output > pedigree. Speed > strategy. Execution is the new Ivy League.

The real edge as an investor?. Finding the weirdos early. Not the polished pitch decks. Not the AI buzzwords. The obsessed ones. They often win—even if they start with a napkin and a dream.

New skill stack:. • Taste.• Speed.• Prompting.• Conviction.• Not losing your mind. Master those, and you’ll outpace 99% of “high-performers” in no time.

AI is the new printing press. Except this time, it’s not just books getting printed — it’s startups. Ideas move at the speed of prompts. Write fast or get forgotten.

Busy founders talk a lot. Great founders disappear. When you’re in flow, the world goes quiet. Less calendar. More output. Shut up and ship.

You don’t need more hours. You need fewer morons in your calendar. Subtraction is the secret weapon. Cut. Cut. Cut. Then build like hell.
