i don't think so a small number of people feel that their life is very happy,others? so can only say that the world is very complicated

beautiful because Your fammily or all people that u love them make u happy Somehow :) .....but life is not beautiful all the time hhhhhhh

Because you made yours beautiful..

you can find what you like ,eat delicious food ,travel throughtout the world. Also, friendship,love,and so many perish things.

because it's so complicated that we make efforts to understand it
