Right, acknowledge the anger and move past it. It's like stress-related issues, your mind/body is telling you that there is a problem that needs to be resolved.

If something repeatedly causes anger or stress it might be a good idea to re-evaluate whether you need that thing in your life. Stuck in a 35-minute queue? It might be time to take your business elsewhere. Angry and motivated often go hand-in-hand.

Fix the problem, don't dwell on the emotion.
