Whether it's anger, jealousy, sadness or discontentment, there's nothing wrong with feeling a certain way.

不管是愤怒、嫉妒、悲伤还是不满，有某种特定的感觉是没有错的。

For example, envy and discontentment can signal that there's a need you're not satisfying for yourself and could be missing from your life.

例如，嫉妒和不满可能表明你的生活中有一种需求没有得到满足，它可能会消失。
