Noticing

Naming what you feel.

Labelling

Putting a specific name to a feeling reduces its intensity and makes it easier to act sensibly. Frustrated, disappointed and anxious call for different responses.

A vocabulary of emotions is genuinely useful; bad and stressed cover too much.
Physical signals often arrive before the label does.

Triggers

Most people have a small number of situations that reliably produce a strong reaction. Knowing yours converts a surprise into something you can prepare for.
