the gods, according to an ancient legend, made choice of certain trees to be under their special protection. jupiter chose the oak, venus the myrtle, apollo the laurel, cybele the pine, and hercules the poplar. minerva, wondering why they had preferred trees not yielding fruit, inquired the reason for their choice. jupiter replied, "it is lest we should seem to covet the honor for the fruit."but said minerva, "let anyone say what he will the olive is more dear to me on account of its fruit." then said jupiter, "my daughter, you are rightly called wise;for unless what we do is useful, the glory of it is vain."

根据古代的传说，众神选择一些树得到他们的特别保护。【被渣男抛弃后小美人沦落街头】“众神之父”朱庇特选择的是橡树，维纳斯选择了香桃木，阿波罗比较偏爱月桂树，库柏勒的选择是松树，赫尔克勒斯决定维护杨树。看到他们选择的都是不会结果实的树木，密涅瓦感到很奇怪，就问他们为什么这样选择。

朱庇特回答说:“我们是不想贪图果实的荣誉！”但是密涅瓦还是不理解，说:“不要去在意别人的评价。我喜欢的依旧是果实累累的橄榄树。”听了她的话，朱庇特说:“女儿啊，你才是真正的聪明。假如我所做的一切没有成果，那荣誉也是徒劳的。”

要做有用的事情。
