My friends say I am happy, but I really don't know what happiness means.

So, what is a happy life? A happy life is actually that you don't have to rush about for this kind of livelihood, that is, you don't have to worry about, er, some daily necessities and these, er, expensive places. Maybe your family is richer, and then you don't have to worry about the rest. We have everything we need and everything we don't need. In this case, you mean where you want to play, where you want to play and what you want to eat.
