Bob Sutton's rule of not being an asshole

Today I came across a little video about Don't be an asshole by Bob Sutton explaining the importance of people learning to be indifferent at times to things that cannot be changed, and ignore those things. It struck me because I tend to get irritated or frustrated about things that I don't like and I don't seem to be able to change.

More on the Don't be an asshole rule on his weblog.
