It is only your action which gives you the meaning of your life. It is only your action which shows you the purpose of your life. You’re born to act.
But not to remain idle. Your action brings you happiness and prosperities in your life. But your inaction brings you unhappiness and adversities in your life. Every living creature on this earth does some action in order to exist.
You’re existed in this world because you’re doing some action in your life.
