Willpower is a limited resource that can be depleted with each successive attempt to use it, but can be replenished.

“ego depletion is the term that Bal Meister used to describe the ability for our willpower to be depleted with each successive attempt to engage willpower and by extension our ability to replenish our degree of willpower if we take a break from making decisions and engaging our willpower”

Discipline and willpower are effective as emergency switches for completing tasks but fail as a long-term foundation for behavior.

“If they're the first things that you're talking about, you just um you're talking about very important, very functional things at the very wrongest point in the hierarchy.”
