Law 40: Despise the Free Lunch

Summary:

What is offered for free often has hidden strings attached — obligations, guilt, or subtle control. Free offerings are rarely truly free; they usually mask a hidden agenda. By accepting them, you risk being trapped or appearing dependent. Instead, it is wiser to pay for what you want and to invest in yourself. Paying your way gives you independence, control, and respect.

Key Ideas:

1. Nothing is truly free – Behind every free offer lies a cost, whether it’s obligation, manipulation, or debt of gratitude.
   Self-reliance earns respect – By paying your way, you show independence and strength. Others are less likely to see you as weak or exploitable.

2. Avoid parasites – People who constantly want “free” things often drain energy and resources. Associating with them diminishes your power.

3. Generosity can be power – When you yourself offer gifts or rewards, it can be a tool of influence, because your free gifts bind others to you.

4. Investment is freedom – Investing your own money, time, or resources creates real value and ensures you are not tied down by another’s agenda.

Reversal of the Law:

While you should despise the free lunch for yourself, strategically giving free gifts or favors can be a tool of power. By making others dependent on your generosity, you bind them subtly and maintain the upper hand.

👉 In short: Avoid what is free when it’s offered to you, but use generosity as a tool to make others dependent on you.
