Jealousy is a common human emotion that can be both positive and negative. When jealousy is positive, it can motivate us to improve ourselves and achieve our goals. However, when jealousy is negative, it can lead to feelings of envy, resentment, and even hatred.
Jealous people are often insecure and have low self-esteem. They may feel threatened by others who they perceive as being more successful or attractive than themselves. As a result, jealous people may try to sabotage others’ success or happiness.
