逛了一天街，晚上想好好在外面吃頓飯，可是拿著菜單看半天也不知道該點什么？嗯，你可能是逛街的時候做了太多選擇，到了晚上，腦子有點不夠用了。

簡單說，你這是“決策疲勞”了。

Decision fatigue refers to the deteriorating quality of decisions made by an individual, after a long session of decision making.
決策疲勞指一個人在做了一長串的決策之后決策質量開始下降的狀態。

It is now understood as one of the causes of irrational trade-offs in decision making. For instance, judges in court have been shown to make less favorable decisions later in the day than early in the day. Decision fatigue may also lead to consumers making poor choices with their purchases.
決策疲勞可能是決策過程中一些非理性妥協的背后原因。比如，法官在下午做出的判決一般沒有上午的判決那么令人信服。另外，疲勞決策還會導致消費者做出一些糟糕的購物決定。

The best solution for decision fatigue is the same as any other type of fatigue—rest. And there are many little steps you can take to minimize the impact of decision fatigue on your spending, your relationships, and your life.
對付決策疲勞的最佳辦法跟對付其他類型的疲勞是一樣的，那就是休息。另外，還有一些小建議可以幫助減少決策疲勞對消費、人際關系以及日常生活的不良影響。

Make vital decisions early in the day.
重要的決策要在早上做。

Save unimportant decisions for later in the day.
不太重要的決定可以留到下午再說。

Avoid situations where you're drawn to impulsive decisions late in the day.
盡量避免在下午被拖入一個會讓你做出沖動決定的場合。
