I remember a quote from Aristotle everytime i get angry...

"Anybody can become angry - that is easy, but to be angry with the right person and to the right degree and at the right time and for the right purpose, and in the right way - that is not within everybody's power and is not easy."

this has worked wonders for me... everytime i get angry i think for myself, is it worth being angry and surely the answer is no...

And yes, sometimes if it is worth, then i follow ajay's way... not speak anything and go for a small walk :)
