LESSON 2 · Your Brain on Money
Labor of Love
In 2012, behavioral researchers confirmed something IKEA shoppers already sensed: people value things they build themselves far more than identical pre-built items. Participants who assembled their own IKEA storage boxes were willing to pay far more for them than for the same pre-built boxes. In a companion test, people even prized their amateur origami as highly as expert-made figures — purely because the work was theirs.

This isn't about quality. A wobbly bookshelf you spent three hours building feels more valuable than a perfectly crafted one from a store. Your effort creates emotional attachment. Your brain doesn't separate "I worked hard on this" from "this is actually good."
