Here's a video that's produced in something of a silly, humorous way. However, the advice is good and these suggestions have been well documented to work.
Just because you aren't in a situation, by the way, in which you can do all of these doesn't mean you can't do one or two of them. For example, you can fall back on a mantra you have chosen to use when you're agitated in just about any situation. No one needs to know. I have two that work: "serenity" and "accept without judgment" . The trick is remembering to use them. But don't give up if you forget once in a while. Aim for "progress - not perfection" (as the 12 Step folks say).
