譯文：與其讓鄉(xiāng)鄰夸贊自己，不如讓他們對(duì)自己沒有怨言；與其為子孫謀求財(cái)富和產(chǎn)業(yè)，不如教會(huì)他們受用一生的本事。賞析：我們要做到被人人稱贊很難，但可以做到不被人抱怨。對(duì)方抱怨，肯定是內(nèi)心有不平事。當(dāng)我們動(dòng)之以情，曉之以理，做到公平公正，一視同仁，鄉(xiāng)鄰的怨憤才會(huì)減少。授人以魚，不如授人以漁。我們竭盡全力為子孫后代積攢萬貫家財(cái)，如果他們不會(huì)理財(cái)，家業(yè)遲早都會(huì)敗光。相反，我們教會(huì)他們賺錢的本事，教會(huì)他們做人的準(zhǔn)則，他們自然可以立于不敗之地。
