Greg my old mate. Still going in circles? ha,ha. Just wanted to say I hope you don't believe that arrogant vs confidence quote you made above. That could lead you all kind of wrong places.
Hi, Graham, buddy - Oh, I don't know - IMO, there is difference in the source of both, but their behavioral outputs can appear similar, thereby causing confusion to the casual observer.
As far as circles? yes, all that yin and yang stuff, as you know...
