I've actually been getting really irritated with myself when I make stupid mistakes. Like how many does a person have to make before they learn to not make them? And when you think about it, they're all things that could be easily avoided: pay more attention, don't be lazy in preparing, etc.. it's just a matter of paying attention at the right times and to details. It irritates me that these things still happen to me, and it irritates me that it irritates me
