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 agree with what you have said. For me, it goes beyond happiness, it goes further to fulfillment and satisfaction in life. Happiness is definitely included but it's just a factor to be satisfied in this life. People work hard and put great effort to make sure that they are able to attain their aspirations. In this way, when they are able to meet them, it would give them a sense of fulfillment and satisfaction that will shed light on what is your purpose in life.
