"Bitterness is like cancer. It eats upon the host. But anger is like fire. It burns it all clean."
"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."
"Speak when you are angry and you will make the best speech you will ever regret."
