A working notebook about Life Arbitrage — how a philosophy of arbitrage can open real possibilities in places like Latin America without forcing a binary choice between staying and relocating, unless that’s what you want. Medical, investment, social: some of the areas where the Life Arbitrage mindset changes how you think and live.

I paid $160 for a top-floor Airbnb in Casco Viejo while the trading system ran. The US equivalent would have been $700 to $1,000. That gap isn't the story — the optionality it creates is.
I got my teeth cleaned in Barranquilla, Colombia for thirty dollars. Professional office, modern equipment, the whole deal. And I wasn't even there for the dentist.
The word gets used as a synonym for "deal" or "hack." It isn't. Arbitrage has a specific meaning, and getting it right changes what you do with the idea.
