Optimism is the best quality of humanity. For a person, being optimistic is very much essential if he wants to lead a happy and healthy life. It is important to understand that life is full of ups and downs. Sometimes we are happy and sometimes sad. Human life may suffer from different kinds of problems in life. Instead of leading a monotonous life, it is preferable to face the issues and try to find the solution to all the problems in life. Optimism is such a quality that always helps to find a solution for any problem. If a person continues to be pessimistic, it becomes difficult to live a peaceful life. Thus, it is always important to be an optimist rather than a pessimist to lead a happy and carefree life.
