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?
Happiness is one of the goals of humans. Enjoying life to the fullest.
Falling in love. Making friends. That is what make humans happy.
