Two of the most destructive emotions are envy and jealousy, both of which stem from the same source:our own insecurity. 两种最为消极的情绪就是嫉妒和妒忌,两者的根源相同：我们的不安感。

As we dive into this lesson, let's first make sure we are clear on the definition of both terms. 开始深入这个课题之前，我们首先来弄清楚这两个词的定义。

What is envy? According to Wikipedia envy is best defined as an emotion that occurs when a person lacks another’s (perceived) superior quality, 什么是嫉妒。根据维基百科上的解释。嫉妒最好的解释是当一个人缺少别人的某些可观的优秀品质、

achievement, or possession and either desires it or wishes that the other lacked it. 成就或者拥有物时，产生的一种想要得到或者希望别人也得不到的情绪。

Envy can also derive from a sense of low self-esteem that results from an upward social comparison threatening a person’s self image:  嫉妒也可能来源于因为对比上层社会而觉得自身形象受损产生的自卑心理，

This is where another person has something that the envier considers to be important to have.  (嫉妒者)认为上层社会的人拥有一些他们觉得很重要的东西。

If the other person is perceived to be similar to the envier, the aroused envy will be particularly intense,  如果拥有者看上去和那些嫉妒者相似，那么激起嫉妒心的人就会尤其紧张，

because it signals to the envier that it just as well could have been he or she who had the desired object. 因为他们觉得自己也(有资格)能拥有这些自己想要的东西。

Bertrand Russell said “envy is one of the most potent causes of unhappiness.  勃兰特·拉塞尔说过：“嫉妒是不开心最主要的原因之一。

It is a universal and most unfortunate aspect of human nature because not only is the envious person rendered unhappy by his envy, but also wishes to inflict misfortune on others.” 它是人性中很普遍也是最不幸的一面因为它不仅使得嫉妒者不开心而且它还使嫉妒者希望将不幸加于别人身上。”

Let's take a look at what Wikipedia says about jealousy. 我们来看看关于妒忌维基百科是怎么说的。

Jealousy is an emotion and typically refers to the negative thoughts and feelings of insecurity, fear,  妒忌是当产生消极想法和不安全、害怕、

and anxiety over an anticipated loss of something that the person values, such as a relationship, friendship, or love.  渴望得到自己珍视的亲情、友情和爱情时的一种典型的情绪。

Jealousy often consists of a combination of emotions such as anger, sadness, and disgust. It is not to be confused with envy. 妒忌通常包含这几种情绪：生气、伤心和厌恶。它不同于嫉妒。
