When you are feeling a feeling, name it so it doesn't control you.

Point at it, hold it.

Acknowledging it allows you to hold it at arm's length and move it to a has-a relation.

If you don't, then it is implicitly part of you (is-a) and can have strong implications for how you act that are often not what you want to want.

Don't ignore emotions. Name them, label them, hold them as an object.
