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?
I believe yes , happiness is our main goal in life. As we strive to achieve our goals and find our purpose in life , happiness is what we really want to achieve. To have the things that we want in life and to live a happy life, is what everyone aims to be and to have. To be happy and joyful is everybody's dream.
