At each stage, decisionmakers must ask themselves questions, such as whether they have the relevant experience and expertise to make their choice, and whether the option they favour is practical.

在每段，决策者都必须扪心自问，比如自己是否具备做出择所需相关经验和专业知识，以及自己青睐择是否切实可行。

People – far-sighted, rational decisionmakers – aim only to maximize self-interest.

人们——有远见、理性决策者——只以自身利益最大化为目标。
