How energetic a person am I?
It all depends on what kind of energy we're talking about... Let's just say it's my subjective sense of energy.
But it still all depends. Who am I hanging out with, and what have we been talking about? (If it was a group, my energy level has probably plummeted--or rather, a foot-tapping and chocolate-eating kind of anti-energy has probably polluted me.) How much did I sleep, and what did I dream? What have I been eating? (If it was all vegetables and fruit, with healthy doses of spice, I should be feeling great.) Is it sunny outside? Does my apartment feel inhabited?
I don't think that my identity/self/soul has an energy level, as though the essence of my being were an electron getting bumped up and down the orbitals as it spins wildly around the nucleus (the kernel of life?). No, neither lethargy nor euphoria are intrinsic to who I am. I think that what is intrinsic to who I am is, rather, the predictable ways that my energy level rises or falls in response to particular situations.
As far as outward manifestations of that energy level, though, I am consistently closer to "calm and quiet" than to the loud, fast-moving energy that I associate with a sugar-high. When people try to say what kind of animal I would be, they never name the twitchy, jumpy animals, like squirrels or frogs or dalmatians or gazelles. Instead, they tell me I am a pony, or (my favorite) a red panda.*
*and then there's the one person who has called me a whale and a stegosaurus... but I'm taking those out of context.
