Unshaped

I could overload, I could underwhelm I'm the wrong person for a job at the helm Throw me to the lions, it's all I'm owed I could underwhelm, I could overload It's a riddle today, as I sit all uneasy I'm all together bothered, not at all breezy Cannot articulate what I'd like to say As I sit all uneasy, it's a riddle today Banish me to a tower, let me out when I sing Reward and punishment an untried thing I need shaping up by an external power Let me out when I sing, banish me to a tower I sink or swim, there's no treading water I am the child of a reckless daughter Fix myself up by sailing off on a whim There's no treading water, I sink or swim
