Wow! What a Great Question! This one really makes you think!
Well, I think it is a mix of both.
I can't face the present without consulting the past.
I assume that I face life with a new outlook influenced by old experiences.
There are many things that I would change or do different, if I was given the opportunity to do it all over again.
With that said, and since I can't (change the past), I look forward to making better decisions in the present and future.
I think that unless I forgot everything in my past, I couldn't move on or do better today.
In short, my future reflects my past; I can not have one with out the other.
