People live to find happiness.
People live to earn much money.
People live to get fame.
People live to find the meaning of love.
People live to have a happy family.
People live to work.

What if they can't find happiness?
What if they can't earn much money?
What if they can't be famous?
What if they can't find the meaning of love?
What if they don't have a happy family?
What if they can't get job?

If people only live for impermanent things in this world,
even they find happiness,
have much money and become famous,
they will not satisfied.
They will find another purpose.
That's the nature of human: never get satisfied.
