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?
The main goal of human is to live.happiness is secondary. Though happiness should inspire us to live our lives. Living and being happy is main purpose of life.
