Self-control stems from the powers of the soul, which all of us possess. The Talmud tells us that a person's greatness or inferiority is recognizable when he gets angry. The logical person does not lose control of himself. It's like a pressure cooker that has a little hole on the top to release the pressure. If you didn't have that little hole, the pot would explode. One should not bottle up his emotions, because that will cause mental anguish. However, although you have to speak, your tone of voice and how you say things make the difference. Building a [successful life] requires self-control and knowing how and when to speak. We sometimes lose control of ourselves and out of anger, say things that we later regret. Many times the regret does not rectify the damage that was done."
