Imagine your brain as a battery. Each decision you make throughout the day drains a little more of its charge. At first, you're sharp, confident, and decisive. But as the day wears on, that battery dwindles. By the time evening arrives, even simple choices feel overwhelming, and you may start making quick decisions just to be done with it. This is the reality of decision fatigue—a challenge that anyone in a high-stakes role can face. If you’re a business executive, startup founder, or team leader, you know the toll it can take on both performance and well-being.
