There's no such thing as a free lunch.

Author: Milton Friedman

Insight: We all know this feeling: the offer that seems too good to be true, the favor that arrives without explanation, the deal that makes you wonder what you're missing. There's usually a catch because someone, somewhere, is paying for it. The real insight isn't that nothing is free—it's that we often pretend not to understand what's actually being traded. Consider how this plays out in everyday life. A social media platform doesn't charge you money, so it feels free. But you're paying with your attention, your data, your time. A job with an amazing salary but brutal hours extracts payment through exhaustion. Even a well-meaning friend who helps you move is spending energy and sacrificing their weekend. Once you start seeing it this way, you realize the quote isn't cynical—it's clarifying. The most useful version of this idea isn't about being paranoid. It's about being honest. When you recognize what's actually being exchanged—what the real price tag is—you can make better choices. You can decide if the cost is worth it to you. The free lunch exists; you just need to know what you're trading for it.
