No matter how small you are, how unlucky you are, how poor you are..You are just priceless in front of your Creator. Your existence on earth must have reasons behind. He will not create you for nothing.
Each person on earth is contributing to society, organisation and people without we/they realize. So, LOVE yourself. APPRECIATE each of your achievement. Have faith and believe that you are unique from others.
Love yourself, be yourself. Let you define yourself as you are priceless in The Eyes of God.
