For the most part I'm with KK on this. Where I am is a product of the path I've taken, and hence leads to where i'm going. There are certainly things that i'm looking to improve and change about who I am, as there is for anyone.
There are things that I've done that I see have hurt others. Those actions that I've taken in the past, I'm working to get into a position to apologize for and make good on. In that regard also, I'm looking to the past to make things right in the future.
