There’s a book I want to recommend: Street Smarts by Norm Brodsky.
What Changed After Building the Skill
I turned the book’s core framework into a Claude Code Skill. Now, whenever a new partnership opportunity comes in, I run it through the analysis.
The result: many seemingly great opportunities turn out to be money losers when you actually calculate the margins. The promises people make are often hollow.
The book doesn’t teach anything esoteric. It asks a few basic questions:
- What’s the gross margin on this deal?
- After hidden costs, what’s the effective hourly rate?
- Do the other party’s promises come with real guarantees?
- How does the cost structure change at scale?
When the Numbers Are Clear, You Stop Flinching
With this rational analysis framework from the book, I’ve become much calmer when evaluating partnerships.
The numbers are right there. The floor is right there. When you know where you stand, there’s nothing to flinch about. Whatever the other party says is their business. Hold your own scope and that’s it.
A recent real example: a student wanted one-on-one consulting at 60% of my rate. After calculating prep time and follow-up overhead, the effective hourly rate dropped to a third. Not worth it. No agonizing needed — just redirect to the course offering.
Why Turn a Book into a Skill
The benefit of making a book into a Skill is that you don’t have to recall the framework from memory every time a decision comes up. The Skill asks the right questions, applies the right formulas, and gives you numbers. People waver under social pressure and persuasive talk, but numbers don’t.
This book is especially suited for freelancers and solo operators. It doesn’t teach you how to make a fortune. It teaches you how to not lose money.
