Welcome to The School of Knowledge and this week’s paid essay. Each Sunday, I send an essay to help you navigate your personal or professional transition, from those who have tried, failed and succeeded—those with skin in the game. If you want support on implementing the mental models, frameworks, and systems, participate in Q&As and have access to our private chat, consider becoming a paid member.
I recently wrote about Edward de Bono’s Six Thinking Hats—a deceptively simple framework that ensures that assumptions are challenged, ideas are given room to breathe, and facts are separated from biases when making critical decisions. It resonated with a lot of readers because we rarely separate emotion from logic, risk from optimism, or instinct from fact. This framework gives you permission to think in layers, not all at once.
Today, I’m releasing something I’ve been building in the background:
A full AI-facilitated version of the Six Thinking Hats prompt, which is designed for real-world decisions, writing challenges, strategic planning, or helping you become unstuck.
You’ll work through each hat one at a time, get reflective feedback from your AI assistant, and by the end of the prompt, have clarity in what you need to do—without the usual overthinking spiral.
🧠 Introducing: The Prompt Vault
This is the first in a series of premium prompts pulled directly from my essays.
They’re practical, modular, and built for tools like ChatGPT or Claude.
All prompts, including the De Bono prompt, will be available to paying subscribers via the Prompt Vault, which lives on my homepage under the ‘Prompt Vault’ tab.
If my essays are the thinking tools—this is the workshop.
If you’re interested in unlocking the full De Bono prompt and the growing Prompt Vault, consider becoming a paid subscriber below. If not, I’ll see you inside next week’s free edition.
Until next time, Karl (The School of Knowledge).
