If you've had a fight with your spouse leave your baggage at home. If you are under the gun on a project, don't take it out on a co-worker. Don't get angry just because someone else is. If your co-worker is mad at something or someone, it doesn't mean you have to be angry too. Be aware of your anger signals.
Anger reveals itself physically through a racing pulse, shortness of breath, or pacing.
Check the signs before your anger gets out of hand. Take a breather. Find ways to temper your temper before it flares. Do breathing exercises, take a walk or even do busy work. Write it down.
