不要用已投入成本來作決策

我們經常在做決策時會考慮到過去已經做的決定與已經投下的成本。例如，你很可能會顧及已經投下的成本與各項努力而忌憚于將這樣的項目放棄掉。

但是，這些過去投入的成本已經發生了，你無法挽回。未來的新機會，才是你當下要把握的。

以下幾點，是你把握未來機會，做好當下決策的重要依據：

1.  聽取他人意見。去聽聽一些不曾參與過之前項目決策，也沒有參與這些項目執行的人的意見。
2. 讓自己輕鬆一點。即使是最優秀的管理者都可能發生錯誤的決策，知錯能改，善莫大焉。
3. 不要害怕犯錯。在做決策時，關注在做成決策之過程的品質，而非決策的結果。

Don't use invested costs to make decisions

We often make decisions that take into account the decisions we have made in the past and the costs that have been invested. For example, you are likely to be afraid to give up such a project, taking into account the costs and efforts that have already been invested. 

But the costs of these past inputs have already been incurred and you can't recover them. New opportunities in the future are what you need to take advantage of in the present.

 Here are some of the key things you can do to take advantage of future opportunities and make good decisions right now: 

1. Listen to others. Listen to people who have not been involved in making decisions on previous projects, and who have not been involved in the implementation of these projects. 
2. Make yourself comfortable. Even the best managers can make bad decisions. It's great to know that mistakes can be corrected. 
3. Don't be afraid to make mistakes. When making a decision, focus on the quality of the process in which the decision is made, not the outcome of the decision.
