For me, identifying my most common anger triggers is the 1st step I use in dealing with it. Obviously, there are things that happen that are unplanned. In those cases, sometimes I manage to curb it quickly, and sometimes not so much. In terms of identification of triggers, here are a couple examples of how I deal:

Trigger (car traffic frustrations): This is inevitable around where I live since I'm from a densely populated area with several aggressive drivers, including myself. Since I know something could piss me off, I say "BirdDancer, there will be a driver who does something ridiculous and plenty of aggressive people. What's the point in getting too angry since you know they're out there. Let them go. Be patient. They're stressed, too. Put some music on and "car dance". Maybe you'll entertain them, too.

Trigger (Dad's and Hubby's annoying antics): "BirdDancer, you know they've always been like that. They're never going to change. Why persist in getting angry? Do your own thing. If you can laugh about it, laugh. You definitely have annoying traits, too, and they put up with them.

Trigger (clumsiness): I know that breaking objects is inevitable for me. It's likely from medications. I can either scream and cry when it happens, or instead, laugh. Or if I can't laugh, just stand for a moment and breathe. Then start cleaning it up and move on. If it's really bad, ask hubby to help. He knows you and your clumsiness."

Trigger (airports): I try to convince my husband to choose destinations that involve the least amount of stress. This usually includes picking airports that are small and not so busy, or are less chaotic. Definitely not London Heathrow! Sorry, London! As for coming back to the US to our evil huge airport, it goes back to the scream or cry. Just take it moment by moment. We also got TSA Pre-Check, recently. When we travel more, internationally, we'll go for the Global Entry.

Trigger (travel stress): I've learned that a calmer itinerary with plenty of breaks and time for myself in the hotel to relax, is necessary. I must keep to a set schedule. If it's too hectic, I'm the Tasmanian Devil from Hell and I will get sick!

Trigger (pantyhose): Wear them as infrequently as possible.

Trigger (news): Avoid it when it gets to be too much. Try to do positive things (even small things) to make the world better. I write to my congressmen. I vote. I contribute little amounts to causes I care about. Even $5. Instead of cursing people for littering, I spend an afternoon with hubby picking trash up. Sometimes strangers thank us.

I used to get angry a lot at work because I was under a lot of pressure. I am disabled now. Someday when I can work again, I will try to have a lower stress situation with flexibility.
