Practice self-discipline by restraining anger. When you are tempted to let anger control you today, re-focus and pray.
"I'm telling you to love your enemies. Let them bring out the best in you, not the worst. When someone gives you a hard time, respond with the energies of prayer, for then you are working out of your true selves, your God-created selves." (Matthew 5:44)
“Speak when you are angry - and you'll make the best speech you'll ever regret.” (Dr. Laurence J. Peter)
