I feel like I would connect more with air, but I would choose earth if I needed it for useful purposes. If faces with danger I could use it to escape no matter what I'm in. In a pinch it could help protect myself or my family. In a famine it could be coaxed to help grow food quickly. Air is good for a lot of things, but earth strikes me as the most powerful.
I'd have to say water, because it relaxes me the most and it would be a challenge to master the fluidity of it. Yeah I am most like earth and bond well with it, like sturdy, solid, not up high usually lol etc.. but I always liked water, plus water tastes good and you won't go thirsty, also it makes my favorite element ice.
