What Eker calls the 'financial thermostat'
The central idea of the book is simple to state: each person carries an internal limit for how much money feels "normal" to have, and that limit works like a thermostat. When your balance climbs too far above it, some part of you works to bring it back to the comfortable level.
Think of someone who gets a big bonus and, within a few months, watches it vanish into an expensive remodel, a new car, or a loan to a brother-in-law. It's not repeated bad luck: it's a spending pattern reacting to an amount the person wasn't used to managing.
What matters here is not the thermostat's number itself but the practical implication: making more money without changing your behavior around it tends to put you back in the same place before long, which helps explain why lottery winners often return to their previous financial situation within a few years.
