✿ Multitasking Is Back (And This Time It Actually Works)

Multitasking Is Back (And This Time It Actually Works) You’re becoming a manager whether you like it or not. → And nobody’s teaching you how Here’s the uncomfortable truth about working with AI: The more powerful your AI assistants become, the less time you spend doing deep work and the more time you spend orchestrating multiple tasks in parallel. This isn’t a bug. It’s a feature. But it creates a dangerous new problem: While you’re switching between AI tasks, your brain is getting hijacked...

Two People, Same Layoff, Different Outcomes (Here’s Why) (The System That Turned My Layoff Into My Launch) Two people get laid off from the same company. Same role. Same expertise. Same years of experience. One spirals ... sending hundreds of resumes, getting ghosted, questioning everything. The other launches a business within months. What’s the difference? Last year, I was person number two. After 15 years building expertise—from Agile coaching in 2009 to becoming the highest-paid...

The Knowledge Paradox: Why Smart People Stay Stuck The Challenge You’re Facing You’ve built expertise. You’ve accumulated knowledge. You’ve developed insights through years of experience. But here’s what I’m seeing across my community: your knowledge is trapped. It sits in scattered notes, half-remembered conversations, and mental models that never quite make it into actionable systems. You consume more information than ever, yet struggle to transform it into the value you know you’re capable...

Der Lakmustest deines Wissens (und warum 95% durchfallen) Wir haben uns das Erfassen und das Entwickeln angeschaut. Jetzt kommt der Moment der Wahrheit: Erschaffen. Hier eine harte Realität: 95% aller Menschen scheitern am Lakmustest des Wissens. Sie wissen viel. Sie haben entwickelt. Aber sie erschaffen nichts. Kein Artikel. Kein Workshop. Kein Produkt. Keine sichtbare Wirkung. Ihr Wissen bleibt unsichtbar - und damit wertlos. Das Problem: Wissen ohne Wirkung Du kennst diese Menschen....

Warum deine gesammelten Notizen wertlos sind (und wie du das änderst) Gestern hatten wir uns das Erfassen angeschaut. Das eigene Erfassen zu optimieren war der erste wichtige Schritt. Aber was passiert dann mit all den erfassten Informationen? Hier eine unbequeme Wahrheit: 90% aller Notizen werden nie wieder angeschaut. Du kennst das. Du hast hunderte Kindle-Highlights. Dutzende gespeicherte Posts. Ordner voller Artikel-Bookmarks. Und trotzdem findest du nie das, was du brauchst, wenn du es...

Wie ich aufhörte zu sammeln und anfing zu erfassen Der durchschnittliche Wissensarbeiter konsumiert täglich 34 GB an Informationen - das entspricht 100.000 Wörtern. Wieviel davon wird zu nutzbarem Wissen? Weniger als 1%. Bei mir strömen Informationen aus 9 Quellen ein: LinkedIn, Kindle, Newsletter, Podcasts. Früher war das ein schwarzes Loch - rein ging viel, raus kam nichts. Bis ich einen Knoten löste, der alles veränderte. Das Problem: Sammeln statt Erfassen Die meisten Menschen machen beim...

I Failed My Own Learning Test (Then Fixed It) I’m sitting on the train to Leipzig, cracking open “Der weiße Hai im Weltraum” (The White Shark in Space). Page 1, page 20, page 50 - I can’t put it down. No highlighter in sight. No notebook open. Just pure consumption. “This is brilliant!” I think with every story, every insight, every aha-moment. The book is masterfully written, packed with frameworks and revelations that could transform how I approach my work. Five hours later, I’m done....

What if you could cancel that expensive SaaS subscription and build exactly what you need in hours, not months? → This is what happens when vibe coding meets real development knowledge Ten years ago, I was a passionate software developer. Then I followed my calling into Agile coaching, helping teams build better products. The coding passion never died - it just went dormant. Two months ago, it exploded back to life. But this time, something was different. This time, I had vibe coding. The...

Tool-Chaos beendet: Mein 20€ System 2000+ KI-Tools. 15 Wissenssysteme. Ich nutze 2. Und zahle nur 20€ monatlich. Gerade habe ich Perplexity gefragt: “Wie viele KI-Tools gibt es mittlerweile?” Die Antwort: 2000+ einzigartige KI-Tools. Und fürs Managen unseres eigenen Wissens? Dafür gibt es immerhin 15+ verschiedene Systeme. Kennst du diesen Kreislauf auch: Neues Tool entdeckt → Setup investiert → nach 3 Monaten wieder frustriert aufgegeben. Evernote → OneNote → Notion → Roam → zurück zu...

Hey there, Three weeks ago, I was a "former developer" who occasionally wrote scripts. Right now? I'm knee-deep in building my own CRM, learning as I go, and honestly having more fun with code than I have in years. Tomorrow, Thursday at 6PM CEST (12PM EDT), I'm sharing what this journey looks like – including the parts where I still have no idea what I'm doing. Here's where I am right now → Built my homepage with Lovable (felt like magic, then I wanted more control) → Moved everything to...
