Not difficult. You are a Muslim and follower of Muhammad peace be upon him. So pray 5 times in a day because worship of Allah will prevent you from evil acts, and you know anger is an act of evil.
When you feel anger, read Aooz U Billah 3 (complete) times. Drink a glass of water to control.
If you are standing. Sit down. If you are sitting, lay down.
Anger will take away your wisdom &respect as well. So be patient, win the hearts of people and get reward from Allah.
