Not allowing the minor things, which is most things, to draw one's ire is a wise plan of action. Living life with accepting not only the bad but bearing down your focus upon the good is far, far more beneficial.

Speaking from experience, fury and wrath are not two things of anger's domain one should toy with for any extended period in their life. Not letting them consume you makes all things travel that much more fluidly.

Simple, common wisdom I suppose, but I still find myself surprised about the petty vengeance and anger a lot hold over nothing - careless words, for example.
