I'm an artist. I don't look back.

OK. Obviously I do look back. But why?
Is there anything there that will help me on my journey, or am I just wasting time?
I guess I was thinking that looking back and understanding would give me grist for the mill, but, really, what do I want to create? The same old same old?
No. I got at least one foot in the promised land, and lordy lord, I am coming through!
