anger.
Mark Twain had some great quotes like “Never argue with a fool…onlookers may not be able to tell the difference” and “Forgiveness is the fragrance the violet sheds on the heel that has crushed it”.These may be paraphrases, but Mark Twain was keenly aware that the biggest threat to our well being is our own rabid thoughts, and unchecked emotions.I see the danger every day…looking back at me when I brush my teeth.
