求翻译：相对最了解你的人,其实在你一生中不超过3个.很多你认为是知己的人往往经不住考验,因为你对知己要求会很高,同样对方要求也很高.这种朋友可以真正帮助你的事业,帮助也是最大的.这样的朋友有一个就足够了.是什么意思？

Most people who know you, in fact, your life is not more than 3. many of you think is a friend who can't test, because your friend request will be high, the same request is also high. this friend can really help your cause, help is also the largest. friend like one is sufficient.
