What Are we here for?

Sometimes I just think what have i came here for . What is my purpose of Coming to this world??I think when god created me he must have some purpose to which i am here for? I am sure it is not just earning money and having all the materials things in life. Tom if i die what did i do? Looking back at my life I will say thats only what i did? Everybody has some expectations from me . I just cant take it some times.
