If you are expecting gratitude from others for all you did for them then you are heading for unhappiness. It is not in the nature of man to be grateful. Happy people are they who find happiness in helping others and find joy in giving without the tag of expectations. Difficult? Well, isn’t it painful to live with complaints and frustrations? If you are seeking happiness, then live a life of least complaints and more appreciations. People avoid the company of those who are always complaining and love those who are positive and sharing beauty of life!
