A Quiet Mind

Some days my mind gets soaked in desiring to feel pleasantly productive, with thoughts like go, go, go and do, do, do. But I would rather have it soak in the sound of silence, with thoughts like, "The Lord is my shepherd; I have all that I need. He lets me rest in green meadows; he leads me beside peaceful streams." So I wonder, how do I get from point A to point B in a single day?
