You have come into physical form for a purpose:  to express divinity in your unique way.  What is your passion?  When you cannot help but express yourself through that which brings you joy, you have found your purpose.  It need not be anything “great” in terms of human endeavors.  The smallest exchange of love with another is enough to help you feel purpose-full.  Be love.  In doing so, you will know love.  You are so very loved.
