What of those would suit me best? Well, I have to vote for other because I find all those listed elements to bee too narrow and restrictive.
I'm not sure if Mind would count as an element, but I would likely be a combination of Water, Light and Earth. I like things that are in motion, I don't like staying still and yet I can be incredibly stubborn and people have remarked that there is certain immutability in my character. Yet I'm also light-hearted, can't really hold a grudge, willing to help people and generally good-natured. And when I hit problems, I tend to 'flow' around them, rather tackling them in small bits or finding ways to completely bypass those problems.
