Once I get consumed by a thought or idea, once a vision becomes implanted in my brains I'll stop at nothing to ensure that vision is achieved. Regardless of the price I might pay, and it's consequences.
I bother that one day I might gets embroiled in a vision and get burned while trying to achieve it.
