@airwallex Most people struggle not because life is hard — but because they never learn how to think. In this clip, Jack Zhang, founder of Airwallex, explains why critical thinking and first-principles problem solving matter more than talent, hustle, or luck. If you’re in your 20s, save this. This mindset compounds. At 20, the real skill isn’t working harder. It’s learning how to break problems down, think clearly under pressure, and solve from first principles. That’s how durable companies — and durable careers — are built.
