Modern life demands constant decision-making. From mundane choices such as what to wear, to weightier ones about careers or relationships, the process can be exhausting. But not every decision carries the same weight – some are routine and require very little thought, while others are unexpected, complicated or high-stakes, draining far more of our mental energy.
