Nia: I love that! But let's talk about the physical side of this. Sometimes I feel like my willpower just... runs out. Is that real?
Jackson: Oh, it's absolutely real! Roy Baumeister's research in "Willpower" shows that self-control literally runs on glucose-your brain's fuel. When you've been resisting temptations all day, you're actually depleted, like your phone battery running low.
Nia: So that's why I demolish a bag of chips after a stressful day at work, even though I ate salad for lunch?
Jackson: Exactly! You've been using willpower all day-resisting gossip, staying focused in meetings, not checking your phone-and by evening, you're running on fumes. But here's what's fascinating: even though depletion is real, we often have more reserves than we think.
Nia: What do you mean?
Jackson: Well, studies show that people who believe willpower is unlimited actually perform better when challenged. It's partly about mindset. Plus, you can restore willpower through sleep, meditation, and even just taking a few deep breaths to activate your parasympathetic nervous system.
Nia: So it's not just about gritting our teeth and pushing through?
Jackson: Not at all! In fact, "Buddha's Brain" teaches us that harsh self-criticism actually makes things worse. When you slip up and eat that cookie, beating yourself up triggers what psychologists call the "what-the-hell effect"-you end up eating the whole box.
