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?
Human had their own understanding and opinions in life. For example, why most successful business men are not a degree holder but now a tycoon business man like Lucio tan, Henry Sy, but for what they hired mostly was a degree holder? Though, in the mindset of a degree holder was being a degree holder is their key to achieve there dream to become successful someday, just something like that.
