move like you have a purpose

When I was younger my uncle would tell me to do something  like I had a purpose.Now that I'm  older I've  come to realize  that none of us are born to do anything in life.Some of us love,fight,kill,rape,lie,and steal. That's not our purpose,its our choice. Naturally our purpose  is to procreate and that's it.However, In order to do this we have to have a reason to continue  living,what ever that my be.So,maybe hes right in a sense.It's  up to us to create  a purpose  for ourselves in this life.
