Purpose in life

To make the world a better place. But I think this answer would be a very common one, and the ways to make it a better place are so many, that it's a bit meaningless actually.

To love and serve God; to love all of God's creatures; to be a good steward of our talents and abilities.

The Almighty has chosen you, and every other person for
a particular purpose. The aim of life is to understand
the greatness of the creator. And to search for the
purpose for which a soul is given human life. This
purpose differs from person to person because it is
dependent on the past Karma of the soul. It is as
different as our finger prints, no two are alike. But
one thing is sure. Human beings are the highest of all
creation. The rest of the creation is intended for the
use of human beings. All people are expected to enjoy
the creation. Since creation itself is divine, all
people are expected to keep their lives as happily as
possible without interference with others.

Searching to find the purpose of life is a life time task.

When you understand the purpose of your life, then you
will derive the highest happiness of your life.

To evolve as a soul.
