Law 40: Despise the free lunch
What is offered for free is dangerous—it usually involves either a trick or a hidden obligation. What has worth is worth paying for. By paying your own way you stay clear of gratitude, guilt, and deceit. It is also often wise to pay the full price—there is no cutting corners with excellence. Be lavish with your money and keep it circulating, for generosity is a sign and a magnet for power.
