I appreciate having choices and I really appreciate the diversity of this thread. The people here are amazing and the range of discussion is quite stimulating. I do not believe I am being inchoate in presenting any information and have not touched at all upon what I know and don't know. I do think there is a lot more I don't know than there is I know. I think I am confused now, no matter.
Ah! But it's so important to know what one doesn't know! Otherwise we're limited to what one knows, which is quite limited indeed. However, delving into the unknown with both feet leaves one ungrounded, and prone to being swept into chaotic confusion. So ideally, the way forward is to plant one foot solidly into what one knows while boldly reaching out with the other foot, into the unknown. So if you don't know what you know, and even more importantly, know what you don't know, then clearly you're lost, and should probably sit for a moment lest you fall.
Welcome to the Wall Walt! It's refreshing to see new faces as a Newbie.
(Does this mean I get a promotion?)
