“When a person’s speech is full of anger, it is because he or she suffers deeply. Because he has so much suffering, he becomes full of bitterness.”
… reduce anger; it serves as a rehearsal for physically expressing anger (violently) in the future.” Nothing rational has ever been done out of anger.
Learn to fix your own problems. “If you are bored, fix it. If you are lonely or hurt, comfort yourself. If you are jealous, don’t hope that someone will reassure you … reassure yourself.” — Leo Babauta
