Everyone in his life have some motives and objectives which he has to pursue to make his life meaningful. Meaning to live, to be happy and to be motivated with consistency.
Motivation towards the specific objective gives inner peace that comes directly from heart and for being peaceful, one should be grateful to his creator, his GOD, WHO made the whole universe, WHO knows how to run and maintain the discipline among all the features and things having in the universe.
This whole universe is enough to be a man for grateful, blooming flowers, running and walking animals, mountains, lakes, oceans, all are the examples of HIS superiority. A man can never form such things in just by tickling his fingers, Only the Greatest GOD do.
So be grateful for what you have, be sympathetic to everyone as this whole universe is going to die one day.
