We have a lot of decisions to make in our lives: Where to live, what job to pursue, what flavor coffee to drink. Some are obviously more serious than others, but regardless of the frivolity of some choices, we still are constantly making selections on a daily basis. And when we're unsure, it's hard to feel confident that we've made the right one.
Research suggests that when we're always making decisions, we may suffer from what is known as decision fatigue, the New York Times reported in 2011. The more decisions you make throughout the day, the more mentally exhausted your brain becomes.
