What Is the Psychology Behind Decision Fatigue?

Decision fatigue is like when you eat too much candy, your brain gets tired from making so many decisions. Imagine picking a toy every day for a week. By the end of the week, it's hard to decide what to pick next because your brain is full of choices and it just wants to stop thinking. The more decisions we make, the harder it becomes to make good ones later.
