“The way to love anything is to realize that it might be lost.”

Why it was said

Robert Cialdini places this line from G. K. Chesterton at the head of the scarcity chapter of Influence. He borrows it because it compresses the principle the chapter explains: things seem more valuable when they are less available, and the possibility of losing something moves us more than the chance of gaining something of equal worth.

What it actually means

Chesterton meant it as a remark about love and gratitude: we value what we are reminded we could lose. Cialdini turns it into a warning about persuasion. The same reflex that makes a person treasure a fragile thing is the one that 'only three left', 'offer ends tonight' and 'exclusive access' are built to trigger. The feeling is real, but it is set off by the threat of loss, not by the thing itself. So the line works in two directions. Turned on yourself, it can deepen your appreciation for what you already have. Turned on you by a seller, it can make you want something you did not want five minutes ago.

How to use it

1. 1When a deadline or a 'last few' label makes you want something, ask whether you would still want it if there were plenty.
2. 2When a price is 'only for today', walk away and check again a week later; if it has not changed, the deadline was doing the selling.
3. 3Use the principle kindly: once a week, notice one thing in your life you would miss if it were gone.
