When Adults say "Teenagers think they're invincible", with that sly silly smile on their faces, they don't know how right they are. We need never be hopeless, because we can never be irreparably broken. We think we are invincible because we are. We cannot be born, and we cannot die. Like all energy, we can only change shapes and sizes and manifestations. They forget that when they get old, they get scared of losing and failing. But that part greater than the sum of our parts cannot being and cannot end, and so it cannot fail.
But this is a mixture, I can't pretend that my world just revolves around me. It's a circus because we find strange combinations in it that make us laugh and cry, but we're happy to feel them 'cause it means we are alive. And if we're alive we can break the globe and make it ours.
So yes, I think I'm invincible.
