can you elaborate the following happy and sad is 2 side of a coin

Dear Student,
Given below are a few points that will help you frame a complete answer. 

• Happiness and sadness depicted as two sides of coin show the reality of life.
• Life is constituted of both pleasant and gloomy situations.
• One can never find a coin that is one sided. It has two faces and both these faces usually represent a particular image or symbol.
• In the same way, life is a coin that contains happiness and sadness. One cannot avoid the happiness and live in a depressed state. Neither can one demand all happiness and reject sorrow. 
• Therefore to have a perfect balance in life, one must have an equal share of both.
• Thus sadness and happiness are the realities of human life.
