Very nice little essay there. Wish my dad had given me that sort of description of geometry when I was wallowing in it in high school myself. Hindsight being 20/20, I can see that now. It is too easy to get stuck on one way of doing something, think of the the box as it were. I've had to debug (and re-write) Perl scripts that were essentially NT batch command processes because that was the only way the person who was writing it seemed to be able to think.
If you focus too closely on something, you sometimes can't see another way around a particular problem. You almost need to be someone who specializes in generality (or something to that effect :-).
Anyway, very thought provoking.
