I believe that addressing food and clothing is the main goal of mankind. Nowadays, many people in the world are still hungry. Only by solving the problem of food and clothing can people talk about a happy life.
Happiness, being happy is the most important thing that you can give to yourself and also to others, because having this you can get anything you want specially to our dreams and success.
for me its a yes! the main goal of human is happiness whatever human wanted to reach it towards to his/her happiness.
For example why do people want to work? because they want a better life, and if they reach better life they also reach their happiness.
So for you what is the main goal of human?
