It is very important to be happy in life, because if you are not happy, nothing in the world is good for you. A little happiness teaches people to save. The biggest thing in life is to keep yourself happy.It is our duty to do whatever pleases us. Best wishes to you, may you always have a happy day.
I agree, the difficulty sometimes is making sure that one makes oneself happy, and that happiness doesn't then cause someone else to be unhappy.
