Who am I and why am I here?

I haven't really taken a really close look at myself in a long time.  To start this process I thought of what I wanted to do with my life and what direction I wanted to go with my career.  I think this part is important because I believe what your passionate about defines a part of who you are.  I then looked into the morals that I believe in. Since morals are subjective I believe that they are also an important part in finding out what kind of person I am.  Why am I here is a much harder question to answer. I never really thought there was a reason why I am here or the human race for that matter.  I believe I am here to live a good life and leave this world in a better place than when I got here.
