Chasing happiness is a new religion of 21 certury.
You worship it, pray for it, devote your life to it, see it a meaning of life, and get extremely anxious when not feeling you have it. Even though your life is utterly ruled by it, you never realize.
Most of the happiness you go after is rather like "Chimera" whose body is capitalism, tail is social media, and its head is narcissism. With no one noticed, this sneaky and creepy creature has subtly replaced God.
