Not knowing

It really gets to me when I discover blind spots that I fail to cover. Really nothing gets to me more than not knowing, when I think I am supposed to know. The "argh" feeling can be so great that I can be consumed in anger for a while. Anger directed at myself mostly. The last question I want to ask myself is always: why didn't I think of that in the first place? The bloody gap is so bloody obvious, how come you can zoom by and not even notice it? Ok, that's really harsh on myself but I'd rather be harsh than slack off. It's always shape up or get shipped out. Once is enough, and I'd better not overlook something similar again.
