4. Have enough information.

　　Go and get the facts before you make a complex decision. By all means weigh up the pro’s and con’s so that you can get an understanding of what’s behind a choice. But be careful – there’s a huge difference between knowing enough to make a choice, and knowing everything to make a choice.

　　When you feel yourself pursuing every fact or every piece of information before you make a decision, stop yourself. Ask “What do I really need to know to make this decision?” and focus your efforts on getting the best information relatively quickly, rather than pursuing all of the information you could get your hands on given a longer period of time.

　　4.尽可能多地搜集信息

　　在你需要做一个复杂的决定前先去搜集足够的数据。务必在所有支持和反对的两面加以权衡，使你能清晰地了解选择背后的分量。但是请小心，对某事足够了解而做出决定和对某事完全了解而做出决定，两者具有很大的不同。

　　当你感觉你在试图寻找每一点事实或逐一排查信息来作出你的选择时，请暂停。问一下自己“要作出这个选择我真正需要知道的是什么？”相对于逐一地搜寻所有的信息，迅速且集中地找一些相对而言比较重要的数据将会省下很多时间。
