Introduction: 
Heraclito said a long time ago " our envy always last longer than the happiness of those we envy", but it seems that centuries later we haven't learnt it yet. Envy is one of the most dangerous feelings and it just reflects our complexes, it leads to a miserable and solitary life and it can make people become their worst enemies.

Conclusion: 
To summarize, we need to try very hard to avoid envy because nothing good can be carried if our strongest feeling is based on not enjoying our own life and not trying to change what we don't like, but just complaining about others' succeed .
