I first learned this in a Buddhist book, and that was in reference to habit energy, but this is the phrase:

"Hello anxiety, today we're going to ___"

If I feel anxious, I often find it paralyzing. I'll try to wait for the feeling to go away before carrying on with life; I'll postpone even simple things like playing a game or showering. Saying this phrase out loud helps me get started doing an activity, which of course then reduces my anxiety.

It was a therapist long ago who told me to try bringing my anxiety with me rather than box myself in until it eventually resolves (which can take days in that state). She reminded me that anxiety is not incompatible with life, and certainly not incompatible with the things I enjoy.

But I didn't know how to apply what she'd said until I learned to say this phrase out loud to myself when I'm feeling stuck.

I hope this helps someone like it helps me.
