It isn't the big purchases that undo you. It's the small, forgettable leak you've stopped noticing you spring.

The thought behind it

Some things stay heavy because they have no name. This line supplies one, and the weight becomes something you can hold. Money Mind is less about earning more than about noticing what each amount was quietly standing in for. Watch what “leak” does here. Change it and the sentence becomes comfortable again, which is how you know it matters.
