I do, in fact, believe in karma as doing something of good today or something in your past will bring you positive influence in the future. I like to think of this phenomena as cause and effect related where destiny follows in the footsteps of the effect from the causal action. I think I believe in Karma mostly because I am a spiritual person and there is just something so satisfying about making someone's day... what goes around will likely come back around in spite of Karma
