If you find yourself feeling angry then what one should avoid is to act on the heat of the moment. Pull out from it, make the environment calm and begin to change your perspective. Making something quiet in your ear or changing the environment triggers the possibility and clarity switch. What used to make you angry will no longer make you angry, you get transported into a state of possibility where you are able to respond wisely. It just moves the focus from the possibility of frustration to the brightest aspect of learning about the matter.
