The principle for Day #46 on the 101-day book report says: "Keep a journal of the things that annoy you about others. Then review it on occasion and consider how judgmental it is to condem the world for not being the way you want it to be."
I see the point here, but I can just imagine people's reaction to me pulling out a pen and paper whenever i got pissed off:
"Hey, pinhead. What are you writing there--a hit list?"
