That is a very succinct summary, thank you for that.

I was actually asking about this from the opposite person's perspective. I didn't catch the "in sales" part -- did I just miss that, or am I missing a larger context of his theory? Having missed that piece of info, I was wondering what this theory says about my own motivations (I would categorize myself in the 3rd category, where I try to help my friends. But shouldn't I question my own motivations, given this outlook?)

I suppose it's reasonable to question one's own motivations pretty regularly, anyhow.

Thanks. I just assumed if value is being transferred, as money/assets rather than experience or knowledge or something else intangible, then the transfer involves "selling". That is just my default assumption in business.
