This is a Buddhist technique, I think, Witz. It helps us to climb down from that too-wound-up-to-think feeling.
So, you take a smooth, deep breath. Gently and easily, as though you had all the time and all the peace in the world, say: "I never did mind, about the little things." Then, smile.
That's it.
It helps me, sometimes. When I can remember to do it.
:O)
Another simple thing is to say, while you are in the shower: "Grasp the vine. Cup your hands and...drink." It will center you. I usually have a little sip of shower water, too. I swear, it always tastes like perfect water. I think it works because it stops that rush, rush, rush feeling of trying to get ready.
