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 same. Happiness is the main goal of everyone. We fight for our own happiness. What we do now is because we want to achieve something that will complete our life. Happiness is the fruit of our love to others, respect, success, friendship and many positive vibes in around the world.
