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?
main goal of life in human is actually finding the meaning of their life. why some people die while you are still alive? it is because you have a role to play in this world. once you find true meaning of your life, you will be happy as well.
