We make decisions every day, but we don't often think about the toll those decisions have on us. Deciding between too many options will drain our mental capacity, as will making momentous decisions that we might regret, or making too many small decisions. For people who make decisions for a living, this stress can cause problems for everyone. But we can do things to reduce that cognitive load, like recognizing the triviality of small decisions and not stressing about a decision after the fact.
