Everything you think you own, everything you love and want, everything you have touched and desired, is not yours.  It will pass on to its next owner, to its next destination after you are no longer here.  All your acts, all your in actions, will still be here, although they will only exist as ripples.  Ripples lapping on distant lives that do not know where they came from.  So why are you here? Why do you try? Why do you act?  Because you are a unique collection of DNA that will never exist again.  You are a unique pattern of energy, and energy does not die, it simply changes. Because your life has meaning, even if it is only to you.
