I spent 15 years taking notes for it.
I spent 41 years picking stocks for it.
I spent 6 months writing it (and loved every moment).
I hope you’ll love it too. 📗
My aim with Rule Breaker Investing is to make YOU:
Smarter, Happier, and Richer.

Pyrite is called fool's gold: it looks valuable and isn't.
We're reclaiming the term.
Fool's Gold is a new series: 3 questions with the people behind the foundation. First up, ED George Khalaf on tennis, Beirut, and the one goal Americans still agree on. hubs.la/Q04ljcV20

After Japan battled the Netherlands to a 2-2 draw, the Japanese fans stayed behind and cleaned up every single piece of trash from their section at Dallas Stadium after the game.

Clarity Burke spent years teaching kids. Now she's building the Freedometer so students actually feel ready to invest before the real world asks them to.
That moment when an 18-year-old thinks "I can do this" — that's the whole thing. 🎓

“But as Malcolm Gladwell argues in How David Beats Goliath, if you compete with Goliath by playing by his Rules, you'll lose. The only way to win is, like David, to break the rules. To take the road less traveled. Or put another way: to play the Fool in a world of Wise Men.”

It’s Evolving just like @DavidGFool likes to see,
Axon’s drone expansion via Axon Air and Dedrone delivers faster responses (under 2-3 min), handles 65% of calls first and clears 25% without officers, cuts use-of-force by 50%.
Furthermore, boosts safety with Fusus integration and 9km BVLOS, optimizes resources, secures airspace with 300% revenue and 500% bookings growth, strengthens moat via data/AI, drives 30% company growth, and expands TAM with TAM with NDAA compliance.
Evolving its #consciouscapitalism.

If you can find...
- The top dog and first-mover in an important, emerging industry.
- With a sustainable competitive advantage.
- Stellar past price appreciation.
- Good management and smart backing.
- And strong consumer appeal.
... and, some guy from CNBC or The Wall Street Journal is telling you it’s: “OVERVALUED.”
To me? You’ve heard and seen all you need.”
