I'm not big on focus anyways. Oh sure, like the next guy i get annoyed with cheap technology and the endless seduction of gadgets of failure and with my own wide-eyed starry vision of the future that we're actually living now! The point is persistence, of vision, of dogged insight, and not immaculate depth of focus, that's just hocus pocus, and not the way this thing works. 
But i do get pissed at my ineptitude.
