First paragraph: "Really, the difference between the two sorts of people is mental approach and outlook. They're really not two different kinds of people in any outward obvious way, but their mindsets are drastically in opposition to each other. I have seen one and the other, but I don't really see a mix of these approaches in one person, not where this is concerned."

If you didn't understand what I was conveying here, I intentionally pointed out that they aren't really 2 different KINDS of people (the title is a hook, obviously), because people are outwardly varied and nuanced. But the MINDSETS are opposed. Meaning, I can't be in both mindsets at the same time. One day I am in one sort of mindset, perhaps, and maybe the next day or week I am not in that mindset. My last sentence of saying I don't SEE a mix of these in people is not a statement of "objectively people are not mixed on this", it means what I said it means-- that as a GENERAL rule (emphasis on general), I have OBSERVED that people will have a trend of being mostly in one mindset or the other.
