No one will protect what they don't care about, and no one will care about what they have never experienced.

In science, the most important discoveries often come from paying attention to the unexpected.

译文：人贪心不足，就像小蛇想吞掉大象一样，世间的事情就像螳螂捕蝉黄雀在后一般。赏析：贪得无厌只会祸患无穷，人生最大的祸事就是不懂得满足。处处算计别人，事事喜欢占人便宜，最后都会被别人算计。
