Feelings are notifications, not commands. Read them, then decide what to do.

A feeling is information arriving, not an instruction being issued. Anger says something matters, nerves say something is at stake, boredom says the thing is not holding you, and none of them arrive with a required action attached. Trouble starts when the gap between feeling and doing shrinks to nothing. Widening that gap by a few seconds is most of what people mean by being level-headed.

Practice on something small this week: notice the feeling, name it in one word, then choose the response on purpose. You are not overruling anything or pretending to be calm. You are reading the message before you reply to it.
