Quote from Tsing Tao:
violent anger (want to hit/kill/punch/shoot someone) blinds me. anger at my situation, or the country's situation, or stress related to it sharpens my mind to the point where the world is crisp and clear, because i know what must be done.
this is the latter.
Okay, so some anger clouds your judgment but this is a good anger which clears your thinking. Could be.
For me it doesn't.
