I've Been Thinking Again

Sometimes, I wonder ..Why am I here?  Well not just me, all of us.  What is our purpose?  Why is our planet? Maybe I over think things, but I feel like there must be a solution somewhere.  Do I have a purpose, or is this it? What happens when you realize, you have nothing.. and it's never going to change?  Even thought I'm young, I've noticed, for the most part people get what they deserve.  Seeing as this is what I have, what I deserve, I contemplate my logical next step.  Do I continue on trying to figure out exactly what I did? Or do I stop now, with the knowledge to become a better person? I mean, if we do come back.  I think we do.  I think we are put where we are in live because we deserve a reward or punishment for what our soul has done.  So do I continue being as good as I possibly can with hopes that next time will be better, or do I go now, starting over?  Starting off my next passage as  kind and honest.  Retaining the knowledge of how to be an overly good being?
