Yes, willpower can run out—or at least wear down temporarily, a concept known as “ego depletion.”

Here’s what research and psychology say:

🧠 Willpower is like a mental muscle: The more you use it (resisting snacks, staying focused, avoiding distractions), the more fatigued it gets—at least in the short term.
🥱 Ego depletion: Early studies showed people had less self-control after mentally taxing tasks. For example, after resisting cookies, they gave up quicker on puzzles.
🍎 Low energy = low willpower: Your brain needs fuel (especially glucose) to maintain self-control. That’s why decision-making and discipline often crash when you're tired or hungry.
💪 BUT—willpower can be trained: Like muscles, it grows stronger with consistent use. Mindfulness, good sleep, and routines reduce the need for constant self-control.

✨ Bonus: People who believe willpower is unlimited tend to perform better under pressure. So your mindset actually shapes your stamina.
