text: how do you know what is your purpose in life? i believe we must be here on earth for a purpose...but how do you find that purpose of life and my reason for living?  there must be more to life than eating, sleeping, making love, working, and fun....please help me understand!!!! i was always taught that you are here to know, love and serve god. there are many ways to do this. being a good decent person and compassionate to others is a good start.
